HST/ACS Coronagraphic Imaging of the AU Microscopii Debris Disk
John E. Krist, D. R. Ardila, D. A. Golimowski +5
We present {\it Hubble Space Telescope} Advanced Camera for Surveys multicolor coronagraphic images of the recently discovered edge-on debris disk around the nearby ( pc) M…
Cluster Galaxy Populations from z=0.33 - 0.83: Characterizing Evolution with CL1358+62
Kim-Vy Tran, Garth Illingworth, Marijn Franx
We combine HST WFPC mosaics of clusters at multiple redshifts with Keck LRIS spectroscopy to characterize different galaxy populations and how they evolve. By combining quantitativ…
Evolution of Cluster Early-Type Galaxies
P. G. van Dokkum, M. Franx, D. D. Kelson +2
The slow evolution of the M/L ratios, colors, and line strengths of cluster early-type galaxies to z=1 suggests that their stars were formed at very high redshift. At the same time…
Type Ia Supernovae and the Value of the Hubble Constant
Brad K. Gibson, Chris B. Brook
The methodology involved in deriving the Hubble Constant via the calibration of the corrected peak luminosities of Type Ia supernovae (SNe) is reviewed. We first present a re-analy…
Luminous red mergers in the z=0.83 cluster MS1054-03: Direct evidence for hierarchical formation of massive early-type galaxies
P. G. van Dokkum, M. Franx, D. Fabricant +2
We present results from a morphological study of the distant X-ray cluster MS1054-03 at z=0.83. We have obtained a large, two color HST WFPC2 mosaic of this cluster, and measured r…
The Hubble Constant from the HST Key Project on the Extragalactic Distance Scale
Laura Ferrarese, Brad Gibson, Daniel Kelson +14
The final efforts of the HST Key Project on the Extragalactic Distance Scale are presented. Four distance indicators, the Surface Brightness Fluctuation method, the Fundamental Pla…
