GO 14069: Searching For Multiple Populations in Massive Young and Intermediate Age Clusters
HST image of the LMC cluster, NGC 1866 |
Globular clusters are remnants of the first substantial burst of star formation in the Milky Way. With typical masses of a few x 105 solar masses, distributed among several x 106 stars, the standard picture holds that these are simple systems, where all the stars formed in a single starburst and, as a consequence, have the same age and metallicity. Until recently, the only known exception to this rule was the cluster Omega Centauri, which is significantly more massive than most clusters and has both double main sequence and a range of metallicities among the evolved stars. Over the past 5-10 years, Omega Cen has been joined by numerous other Galactic clusters, including NGC 2808, which shows evidence for three distinct branches to the main sequence, NGC 1851, 47 Tucanae and NGC 6752 - all relatively massive clusters. In almost all cases, the complexity of these systems has only emerged through the high precision observations possible with HST. Hubble is now being turned towards clusters in our nearest neighbour galaxies, the Large and Small Magellanic Clouds. Previousl observations have obtained of the massive cluster NGC 1846. The present program aims to extends coverage to a dozen other clusters, including NGC 419, 1783, 1850 and 1866. The clusters span a wide range of ages, from ~100 Myrs to close to 10 Gyrs. The WFC3-UVIS camera will be used to obtain UV (F343N, F336W) and blue-band (F438W) images to search for evidence of multiple populations in the colour-magnitude diagrams. |
GO 14497: Identifying z>12 galaxies with JWST: What sources produce strong UV emission lines?
Chandra image of the galaxy cluster RCS 0224-0002; X-ray point sources are flagged |
The James Webb Space Telescope, set for launch in October 2018, is expected to revolutionise our ubderstanding of the earliest epochs of galaxy formation at redshifts z . 10. At those high redshifts, JWST's infrared imaging and spectroscopy will be probing the rest-frome ultraviolet for those young galaxies. The present program aims to provide some insight into the types of galaxies that might produce emission lines at those redshifts. The observations focus on a redshift z=4.87 galaxy that is being lensed by a galaxy cluster, RCS 0224-0002, at z~0.773. This system has been studied extensively by both HST and ground-based telesopes, including, crucially, the MUSE integrated field spectroscopic unit on the Very Large Telescope. Those observations reveal the presence of strong CIV absorption, suggestive of extended star forming regions. The present program will use Hubble to obtain deep imaging in the I-band with the Advanced Camera for Surveys, and in the J and H bands with the Wide Field camera 3 infrared camera. Those images will provide the spatial resolution required to determine the extent of the star forming regions in this galaxy, and help prepare for JWST observations of even high redshift systems. |

The first exoplanet, 51 Peg b, was discovered through radial velocity measurements in 1995. 51 Pegb was followed by a trickle, and then a flood of other discoveries, as astronomers realised that there were other solar systems radically different from our own, where "hot jupiters" led to short-period, high-amplitude velocity variations. Then, in 1999, came the inevitable discovery that one of those hot jupiters. HD 209458b, was in an orbit aligned with our line of sight to the star, resulting in transits. Since that date, the number of known transiting exoplanet systems has grown to more than 100 from ground-based observations, most detected through wide-field photometric surveys, while the high-sensitivity data provided by Kepler has added a further 1000+ confirmed systems and ~2000 additional candidates. Transiting systems not only provide an accurate measure of the planetary radius (at least relative to the parent star), they also provide us with an opportunity to probe the atmospheric composition through spectroscopy during the transit. Hubble has made significant inroads in this area, while Spitzer has contributed measurements of planetary emissivity through observations during and after eclipse. The James Webb Space Telescope has the capability to revolutionise our knowledge in this field through highly sensitiive observations at near and mid-infra red wavelengths. The present program aims to lay the foundation for those programs by using Hubble to compile multiwavelength (UV to near-IR) spectroscopic observations of 20 exoplanets. The targets are all gas giants, ranging from super-jovian masses to neptunian masses. The observations will be obtained with the Space Telescope Imaging Spectrograph and the near-infrared grisms on Wide Field Camera 3. |
