COSMOS : Hubble Space Telescope Observations
N. Scoville, A. Benson, A. W. Blain +50
The Cosmic Evolution Survey (COSMOS) was initiated with an extensive allocation (590 orbits in Cycles 12-13) using the Hubble Space Telescope (HST) for high resolution imaging. Her…
Detection of Nuclear X-ray Sources in Nearby Galaxies with Chandra
Luis C. Ho, Eric D. Feigelson, Leisa K. Townsley +7
We report preliminary results from an arcsecond-resolution X-ray survey of nearby galaxies using ACIS on board Chandra. The total sample consists of 41 low-luminosity AGNs, includi…
Observations and Implications of the Star Formation History of the LMC
J. A. Holtzman, J. S. Gallagher, A. A. Cole +3
We present derivations of star formation histories based on color-magnitude diagrams of three fields in the LMC from HST/WFPC2 observations. A significant component of stars older…
Hubble Space Telescope Observations of the Draco Dwarf Spheroidal
Carl. J. Grillmair, Jeremy R. Mould, Jon A. Holtzman +15
We present an F606W-F814W color-magnitude diagram for the Draco dwarf spheroidal galaxy based on Hubble Space Telescope WFPC2 images. The luminosity function is well-sampled to 3 m…
Weak Gravitational Lensing around Field Galaxies in HST Survey Images
R. E. Griffiths, S. Casertano, M. Im +1
Using data from the HST Medium Deep Survey, a long-term Key Project, together with generically similar archived data, we have discovered evidence for weak gravitational `shear' of…
