HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT # 4244 PERIOD COVERED: UT November 20, 2006 (DOY 324) OBSERVATIONS SCHEDULED ACS/HRC 10833 Host Galaxies of Reverberation Mapped AGNs We propose to obtain unsaturated high-resolution images of 17 reverberation-mapped active galactic nuclei in order to remove the point-like nuclear light from each image, thus yielding a "nucleus-free" image of the host galaxy. This will allow investigation of host galaxy properties: ou ...Continue Reading

HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT # 4237 PERIOD COVERED: UT November 08, 2006 (DOY 312) OBSERVATIONS SCHEDULED ACS/HRC 10556 Neutral Gas at Redshift z=0.5 Damped Lyman-alpha systems {DLAs} are used to track the bulk of the neutral hydrogen gas in the Universe. Prior to HST UV spectroscopy, they could only be studied from the ground at redshifts z>1.65. However, HST has now permitted us to discover 41 DLAs at z<1.65 in our previous surveys. Foll ...Continue Reading
