NICMOS Post-SAA calibration - CR Persistence Part 5
A new procedure proposed to alleviate the CR-persistence problem of NICMOS Dark frames will be obtained immediately upon exiting the SAA contour 23, and every time a NICMOS exposure is scheduled within 50 minutes of coming out of the SAA The darks will be obtained in parallel in all three NICMOS Cameras The POST-SAA darks will be non-standard reference files available to users with a USEAFTER date/time mark The keyword 'USEAFTER=date/time' will also be added to the header of each POST-SAA DARK frame The keyword must be populated with the time, in addition to the date, because HST crosses the SAA ~8 times per day so each POST-SAA DARK will need to have the appropriate time specified, for users to identify the ones they need Both the raw and processed images will be archived as POST-SAA DARKSs Generally we expect that all NICMOS science/calibration observations started within 50 minutes of leaving an SAA will need such maps to remove the CR persistence from the science images Each observation will need its own CRMAP, as different SAA passages leave different imprints on the NICMOS detectors
WFPC2 10915
ACS Nearby Galaxy Survey
Existing HST observations of nearby galaxies comprise a sparse and highly non-uniform archive, making comprehensive comparative studies among galaxies essentially impossible We propose to secure HST's lasting impact on the study of nearby galaxies by undertaking a systematic, complete, and carefully crafted imaging survey of ALL galaxies in the Local Universe outside the Local Group The resulting images will allow unprecedented measurements of: {1} the star formation history {SFH} of a >100 Mpc^3 volume of the Universe with a time resolution of Delta[log{t}]=0 25; {2} correlations between spatially resolved SFHs and environment; {3} the structure and properties of thick disks and stellar halos; and {4} the color distributions, sizes, and specific frequencies of globular and disk clusters as a function of galaxy mass and environment To reach these goals, we will use a combination of wide-field tiling and pointed deep imaging to obtain uniform data on all 72 galaxies within a volume-limited sample extending to ~3 5 Mpc, with an extension to the M81 group For each galaxy, the wide-field imaging will cover out to ~1 5 times the optical radius and will reach photometric depths of at least 2 magnitudes below the tip of the red giant branch throughout the limits of the survey volume One additional deep pointing per galaxy will reach SNR~10 for red clump stars, sufficient to recover the ancient SFH from the color-magnitude diagram This proposal will produce photometric information for ~100 million stars {comparable to the number in the SDSS survey} and uniform multi-color images of half a square degree of sky The resulting archive will establish the fundamental optical database for nearby galaxies, in preparation for the shift of high-resolution imaging to the near-infrared
NIC2 10893
Sweeping Away the Dust: Reliable Dark Energy with an Infrared Hubble Diagram
We propose building a high-z Hubble Diagram using type Ia supernovae observed in the infrared rest-frame J-band The infrared has a number of exceptional properties The effect of dust extinction is minimal, reducing a major systematic tha may be biasing dark energy measurements Also, recent work indicates that type Ia supernovae are true standard candles in the infrared meaning that our Hubble diagram will be resistant to possible evolution in the Phillips relation over cosmic time High signal-to-noise measurements of 9 type Ia events at z~0 4 will be compared with an independent optical Hubble diagram from the ESSENCE project to test for a shift in the derived dark energy equation of state due to a systematic bias Because of the bright sky background, H-band photometry of z~0 4 supernovae is not feasible from the ground Only the superb image quality and dark infrared sky seen by HST makes this test possible This experiment may also lead to a better, more reliable way of mapping the expansion history of the universe with the Joint Dark Energy Mission
ACS/WFC 10886
The Sloan Lens ACS Survey: Towards 100 New Strong Lenses
As a continuation of the highly successful Sloan Lens ACS {SLACS} Survey for new strong gravitational lenses, we propose one orbit of ACS-WFC F814W imaging for each of 50 high- probability strong galaxy-galaxy lens candidates These observations will confirm new lens systems and permit immediate and accurate photometry, shape measurement, and mass modeling of the lens galaxies The lenses delivered by the SLACS Survey all show extended source structure, furnishing more constraints on the projected lens potential than lensed-quasar image positions In addition, SLACS lenses have lens galaxies that are much brighter than their lensed sources, facilitating detailed photometric and dynamical observation of the former When confirmed lenses from this proposal are combined with lenses discovered by SLACS in Cycles 13 and 14, we expect the final SLACS lens sample to number 80--100: an approximate doubling of the number of known galaxy-scale strong gravitational lenses and an order-of-magnitude increase in the number of optical Einstein rings By virtue of its homogeneous selection and sheer size, the SLACS sample will allow an unprecedented exploration of the mass structure of the early-type galaxy population as a function of all other observable quantities This new sample will be a valuable resource to the astronomical community by enabling qualitatively new strong lensing science, and as such we will waive all but a short {3-month} proprietary period on the observations
ACS/WFC 10882
Emission Line Snapshots of 3CR Radio Galaxies
Radio galaxies are an important class of extragalactic objects: they are one of the most energetic astrophysical phenomena and they provide an exceptional probe of the evolving Universe, lying typically in high density regions but well-represented across a wide redshift range In earlier Cycles we carried out extensive HST observations of the 3CR sources in order to acquire a complete and quantitative inventory of the structure, contents and evolution of these important objects We discovered new optical jets, dust lanes, and revealed point-like nuclei whose properties support AGN unified schemes Here, we propose to obtain ACS emission line images at low and high excitation of 3CR sources with z<0 3, both low- and classical high- power radio galaxies, as a major enhancement to an already superb dataset We aim to probe fundamental relationships between warm optical line-emitting gas, radio source structure {jets and lobes} and X-ray coronal halos We will combine our existing UV images with new emission- line images to establish quantitative star formation characteristics and their relation to dust and merging, and with emission-line excitation maps, test theories on ionization beam patterns and luminosities from active nuclei We will seek jet induced star formation and knowing optical emission-line physics, investigate quantitative jet physics The nuclear emission line properties of the galaxies will themselves be established and used as ingredients in continuing tests of unified AGN theories The resulting database will be an incredibly valuable resource to the astronomical community for years to come
ACS/HRC 10878
An ACS Prism Snapshot Survey for z~2 Lyman Limit Systems
We propose to conduct a spectroscopic survey of Lyman limit absorbers at
redshifts 1
7 < z < 2
2, using ACS/HRC and the PR200L prism
We have
selected 100 quasars at 2
3 < z < 2
6 from the Sloan Digital Sky Survey
Spectroscopic Quasar sample, for which no BAL signature is found at the
QSO redshift and no strong metal absorption lines are present at z > 2
3
along the lines of sight
The survey has three main observational goals
First, we will determine the redshift frequency dN/dz of the LLS over
the column density range 16
3 ACS/HRC 10877 A Snapshot Survey of the Sites of Recent, Nearby Supernovae During the past few years, robotic {or nearly robotic} searches for
supernovae {SNe}, most notably our Lick Observatory Supernova Search
{LOSS}, have found hundreds of SNe, many of them in quite nearby
galaxies {cz < 4000 km/s}
Most of the objects were discovered before
maximum brightness, and have follow-up photometry and spectroscopy; they
include some of the best-studied SNe to date
We propose to conduct a
snapshot imaging survey of the sites of some of these nearby objects, to
obtain late-time photometry that {through the shape of the light and
color curves} will help reveal the origin of their lingering energy
The
images will also provide high-resolution information on the local
environments of SNe that are far superior to what we can procure from
the ground
For example, we will obtain color-color and color-magnitude
diagrams of stars in these SN sites, to determine the SN progenitor
masses and constraints on the reddening
Recovery of the SNe in the new
HST images will also allow us to actually pinpoint their progenitor
stars in cases where pre- explosion images exist in the HST archive
This proposal is an extension of our successful Cycle 13 snapshot survey
with ACS
It is complementary to our Cycle 15 archival proposal, which
is a continuation of our long-standing program to use existing HST
images to glean information about SN environments
ACS/HRC 10860 The largest Kuiper belt object The past year has seen an explosion in the discoveries of Pluto-sized
objects in the Kuiper belt
With the discoveries of the methane-covered
2003 UB313 and 2005 FY9, the multiple satellite system of 2003 EL61, and
the Pluto-Charon analog system of Orcus and its satellite, it is finally
apparent that Pluto is not a unique oddball at the edge of the solar
system, but rather one of a family of similarly large objects in the
Kuiper belt and beyond
HST observations over the past decade have been
critical for understanding the interior, surface, and atmosphere of
Pluto and Charon
We propose here a comprehensive series of observations
designed to similarly expand our knowledge of these recently discovered
Pluto-sized and near-Pluto-sized Kuiper belt objects
These observations
will measure objects' sizes and densities, explore the outcome of
collisions in the outer solar system, and allow the first ever look at
the interior structure of a Kuiper belt object
Our wide field survey
that discovered all of these objects is nearly finished, so after five
years of continuous searching we are finally almost complete in our
tally of these near-Pluto-sized objects
This large HST request is the
culmination of this half-decade search for new planetary-sized objects
As has been demonstrated repeatedly by the approximately 100 previous
orbits devoted to the study of Pluto, only HST has the resolution and
sensitivity for detailed study of these distant objects
ACS/HRC 10853 M82 as a Fossil Starburst: Probing the Super Star Cluster Content of
Region B The importance of M82 as a benchmark for starburst studies has been
recognised by the STScI- sponsored ACS/WFC mosaic of M82 in the B, V, I
and H alpha filters
This proposal supplements this unique legacy
dataset by obtaining U-band observations {F330W filter} of the fossil
starburst region B in M82
This region is rich in compact intermediate
age {~ 1 Gyr} star clusters
The combination of U-band photometry with
the ACS/WFC STScI BVI survey and archival NICMOS JH data will allow us
to derive accurate ages, luminosities and masses for this rare
population of intermediate age massive star clusters
The U-band is
essential for determining ages of clusters < 2 Gyr old because it
measures the depth of the Balmer jump
We will use these data to
determine the true shape of the cluster luminosity function {CLF} for
the M82-B fossil starburst region and thus address the question of
whether young massive clusters will eventually become globular clusters
NIC2 10849 Imaging Scattered Light from Debris Disks Discovered by the Spitzer
Space Telescope around 21 Sun-like Stars We propose to use the high-contrast capability of the NICMOS coronagraph
to image a sample of newly discovered circumstellar disks associated
with Sun-like stars
These systems were identified by their strong
thermal infrared {IR} emission with the Spitzer Space Telescope as part
of the Spitzer Legacy Science program titled "The Formation and
Evolution of Planetary Systems" {FEPS, P
I
: M
Meyer}
Modeling of the
thermal excess emission from the spectral energy distributions alone
cannot distinguish between narrowly confined high-opacity disks and
broadly distributed, low-opacity disks
By resolving light scattered by
the circumstellar material, our proposed NICMOS observations can break
this degeneracy, thus revealing the conditions under which planet
formation processes are occuring or have occured
For three of our
IR-excess stars that have known radial-velocity planets, resolved
imaging of the circumstellar debris disks may further offer an
unprecedented view of planet-disk interactions in an extrasolar
planetary system
Even non-detections of the light scattered by the
circumstellar material will place strong constraints on the disk
geometries, ruling out disk models with high optical depth
Unlike
previous disk imaging programs, our program contains a well-defined
sample of ~1 solar mass stars covering a range of ages from 3 Myr to 3
Gyr, thus allowing us to study the evolution of disks from primordial to
debris for the first time
The results from our program will greatly
improve our understanding of the architecture of debris disks around
Sun-like stars, and will create a morphological context for the
existence of our own solar system
This proposal is for a continuation
of an approved Cycle 14 program {GO/10527, P

ACS/WFC 10813 MgII Absorption Line Systems: Galaxy Halos or the Metal-Enriched IGM? MgII QSO absorption lines detected in the spectra of background QSOs
were used over a decade ago to infer that all redshift z > 0
2 galaxies
have gaseous halos of radius ~ 60 kpc
The actual size of the halo was
believed to be proportional to the luminosity of the galaxy
However,
these conclusions are now much harder to understand in light of the
results from numerical simulations which show how gas evolves in the
universe
These models predict that gas and galaxies merely share the
same filamentary structures defined by dark matter
If these models are
correct, how are MgII systems and galaxies really related? We can better
understand the distribution of absorbing gas if we FIRST select galaxies
close to QSO sightlines and THEN search for MgII absorption at the
redshift of the intervening galaxies
This is the antithesis of the
original experiments which sought to find absorbing galaxies based on
known MgII systems
The frequency with which we detect MgII lines from
randomly selected galaxies should enable us to better understand if
absorption arises in the halos of individual galaxies, or if MgII merely
arises in the same IGM that galaxies inhabit
We have used ground-based
telescopes to indentify twenty z = 0
31-0
55 galaxies within 14-51 kpc
of a g < 20 QSO, and to search for MgII absorption at the galaxies'
redshifts
Surprisingly, we find that only 50% of our QSOs show MgII
absorption
In this proposal, we seek multi-color ACS images of twelve
of the fields to i} correlate the incidence of MgII with galaxy
morphology; ii} determine if absorption {or lack thereof} is related to
galaxy disks or halos; iii} search for signs of galaxy interactions
which may explain the large cross-sections of MgII systems; and iv} look
for faint interloping galaxies closer to the line of sight than the one
we identified
An important component of the program is to observe each
field in the SDSS g-, r- and i-bands, to permit an estimate of the
photometric redshift of any objects which lie closer to the QSO
sightline than the identified galaxy, and which might actually be
responsible for the absorption
ACS/HRC 10801 Direct Determination of Kuiper Belt Object Diameters with HST When it comes to fundamental properties of an astronomical object, it is
difficult to think of a more fundamental physical property than its
size
Because of their distance, objects in the Kuiper Belt are
generally too small for their disks to be resolved
The heterogeneous
albedo and color of the Kuiper Belt population makes size estimates from
observed absolute magnitude highly uncertain
And the long-awaited data
from the Spitzer Space Telescope suffers from our ignorance of crucial
macro- and micro-physical properties such as spin period, pole
orientation, surface roughness, and thermal inertia
We propose to add a
new dimension to the measurement of KBO diameters by employing two
techniques that will directly measure the diameters of three large KBOs
We expect to obtain diameter measurements with uncertainties of 10% or
better and utilize these to validate and cross calibrate the growing web
of diameter measurements for KBOs
ACS/HRC 10800 Kuiper Belt Binaries: Probes of Early Solar System Evolution Binaries in the Kuiper Belt are a scientific windfall: in them we have
relatively fragile test particles which can be used as tracers of the
early dynamical evolution of the outer Solar System
We propose to
continue a Snapshot program using the ACS/HRC that has a demonstrated
discovery potential an order of magnitude higher than the HST
observations that have already discovered the majority of known
transneptunian binaries
With this continuation we seek to reach the
original goals of this project: to accumulate a sufficiently large
sample in each of the distinct populations collected in the Kuiper Belt
to be able to measure, with statistical significance, how the fraction
of binaries varies as a function of their particular dynamical paths
into the Kuiper Belt
Today's Kuiper Belt bears the imprints of the
final stages of giant-planet building and migration; binaries may offer
some of the best preserved evidence of that long-ago era
ACS/HRC/WFC 10758 ACS CCDs daily monitor This program consists of a set of basic tests to monitor, the read
noise, the development of hot pixels and test for any source of noise in
ACS CCD detectors
The files, biases and dark will be used to create
reference files for science calibration
This programme will be for the
entire lifetime of ACS
Changes from cycle 13:- The default gain for WFC
is 2 e-/DN
As before bias frames will be collected for both gain 1 and
gain 2
Dark frames are acquired using the default gain {2}
This
program cover the period May, 31 2006- Oct, 1-2006
The first half of
the program has a different proposal number: 10729
ACS/WFC 10703 Life in the fast lane: The dark-matter distribution in the most massive
galaxy clusters in the Universe at z>0
5 We propose two-filter ACS observations of a complete sample of 12 very
X-ray luminous galaxy clusters at 0
5 ACS/WFC/NIC3 10632 Searching for galaxies at z>6
5 in the Hubble Ultra Deep Field We propose to obtain deep ACS {F606W, F775W, F850LP} imaging in the area
of the original Hubble Ultra Deep Field NICMOS parallel fields and -
through simultaneous parallel observations - deep NICMOS {F110W, F160W}
imaging of the ACS UDF area
Matching the extreme imaging depth in the
optical and near-IR bands will result in seven fields with sufficiently
sensitive multiband data to detect the expected typical galaxies at z=7
and 8
Presently no such a field exist
Our combined optical and near-IR
ultradeep fields will be in three areas separated by about 20 comoving
Mpc at z=7
This will allow us to give a first assessment of the degree
of cosmic variance
If reionization is a process extending over a large
redshift interval and the luminosity function doesn't evolve strongly
beyond z=6, these data will allow us to identify of the order of a dozen
galaxies at 6
5 ACS/WFC 10588 The Host Galaxies of Post-Starburst Quasars We propose to use ACS to conduct a snapshot imaging survey of
post-starburst quasars now being discovered in signficant numbers by the
Sloan Digital Sky Survey
Post-starburst quasars are broad-lined AGN
that also possess Balmer jumps and high-n Balmer absorption lines
indicative of luminous stellar populations on order of 100 Myr old
These objects, representing a few percent of the z < 0
5 quasar
population, may be an evolutionary stage in the transition of
ultraluminous infrared galaxies into normal quasars, or a type of galaxy
interaction that triggers both star formation and nuclear activity
These sources may also illustrate how black hole mass/bulge mass
correlations arise
Ground-based imaging of individual poststarburst
quasars has revealed merger remnants, binary systems, and single point
sources
Our ACS snapshots will enable us to determine morphologies and
binary structure on sub-arcsecond scales {surely present in the sample},
as well as basic host galaxy properties
We will be looking for
relationships among morphology, particularly separation of double
nuclei, the starburst age, the quasar black hole mass and accretion
rate, that will lead to an understanding of the triggering activity and
mutual evolution
This project will bring quantitative data and
statistics to the previously fuzzy and anecdotal topic of the
"AGN-starburst connection" and help test the idea that post-starburst
quasars are an early evolutionary stage of normal quasars
ACS/WFC 10551 Gamma-Ray Bursts from Start to Finish: A Legacy Approach The progenitors of long-duration GRBs are now known to be massive stars
This result lends credence to the collapsar model, where a rotating
massive star ends its life leaving a black hole or a highly magnetized
neutron star, and confirms its essential aspects
The focus of attention
now is on the black hole or magnetar engines that power the bursts
Somehow these engines create the most highly relativistic and highly
collimated outflows that we know of, through mechanisms that no current
theory can explain
These astrophysical laboratories challenge our
understanding of relativistic shocks, of mechanisms for extracting
energy from a black hole, and of how physics works in extreme
conditions
The launch of Swift is bringing us into a new era, where we
can make broadband observations that will enable us to study these
fascinating physical processes
We propose here an ambitious,
comprehensive program to obtain the datasets that will become the
standard that any successful model for the central engine must explain
This programs leverages the HST observations to the maximum extent by
our commitment of Swift observations, a Large program at the VLA, and
extensive ground-based optical resources
By studying the engines and
searching for jets in a variety of events, this program will investigate
the conditions necessary for the engine and jet formation itself
ACS/HRC 10508 Orbits, Masses, and Densities of Three Transneptunian Binaries The subset of transneptunian objects {TNOs} having natural satellites
offers unique opportunities for physical studies of these distant relics
from the outer parts of the protoplanetary nebula
HST/ACS is ideally
suited to determining orbits of TNO satellites, resulting in the system
masses
In conjunction with thermal emission observations by Spitzer,
which provides sizes, we can determine the densities of TNOs
Densities
offer a powerful window into their bulk compositions and interior
structures
ACS/WFC/NIC2 10496 Decelerating and Dustfree: Efficient Dark Energy Studies with Supernovae
and Clusters We propose a novel HST approach to obtain a dramatically more useful
"dust free" Type Ia supernovae {SNe Ia} dataset than available with the
previous GOODS searches
Moreover, this approach provides a strikingly
more efficient search-and-follow-up that is primarily pre- scheduled
The resulting dark energy measurements do not share the major systematic
uncertainty at these redshifts, that of the extinction correction with a
prior
By targeting massive galaxy clusters at z > 1 we obtain a
five-times higher efficiency in detection of Type Ia supernovae in
ellipticals, providing a well-understood host galaxy environment
These
same deep cluster images then also yield fundamental calibrations
required for future weak lensing and Sunyaev-Zel'dovich measurements of
dark energy, as well as an entire program of cluster studies
The data
will make possible a factor of two improvement on supernova constraints
on dark energy time variation, and much larger improvement in systematic
uncertainty
They will provide both a cluster dataset and a SN Ia
dataset that will be a longstanding scientific resource
ACS/WFC 10494 Imaging the mass structure of distant lens galaxies The surface brightness distribution of extended gravitationally lensed
arcs and Einstein rings contains super-resolved information about the
lensed object, and, more excitingly, about the smooth and clumpy mass
distribution of the lens galaxies
The source and lens information can
non-parametrically be separated, resulting in a direct
"gravitational-mass image" of the inner mass-distribution of
cosmologically-distant galaxies {Koopmans 2005}
With this goal in mind,
we propose deep HST ACS-F555W/F814W and NICMOS-F160W imaging of 15
gravitational-lens systems with spatially resolved lensed sources,
selected from the 17 new lens systems discovered by the Sloan Lens ACS
Survey {Bolton et al
2004}
Each system has been selected from the SDSS
and confirmed in a time-efficient HST-ACS snapshot program {cycle-13};
they show highly-magnified arcs or Einstein rings, lensed by a massive
early-type lens galaxy
High- fidelity multi-color HST images are
required {not delivered by the 420-sec snapshot images} to isolate these
lensed images {properly cleaned, dithered and extinction-corrected} from
the lens galaxy surface brightness distribution, and apply our
"gravitational-mass imaging" technique
The sample of galaxy mass
distributions - determined through this method from the arcs and
Einstein ring HST images - will be studied to: {i} measure the smooth
mass distribution of the lens galaxies {Dark and luminous mass are
separated using the HST images and the stellar M/L values derived from a
joint stellar-dynamical analysis of each system}; {ii} quantify
statistically and individually the incidence of mass-substructure {with
or without obvious luminous counter- parts such as dwarf galaxies}
Since dark-matter substructure should be considerably more prevalent at
higher redshift, both results provide a direct test of this prediction
of the CDM hierarchical structure-formation model
