Evidence for a Massive Post-Starburst Galaxy at z ~ 6.5
B. Mobasher, M. Dickinson, H. C. Ferguson +26
We present results from a search for high-redshift J--band ``dropout'' galaxies in the portion of the GOODS southern field that is covered by extremely deep imaging from the Hubble…
Cluster Evolution Since z~1
R. Demarco, J. P. Blakeslee, H. C. Ford +8
We have used the Advanced Camera for Surveys (ACS) on the HST to obtain optical imaging of a sample of 8 galaxy clusters in the redshift range 0.8 < z < 1.3. The ACS data provides…
UV Continuum Spectroscopy of a 6L* z=5.5 Starburst Galaxy
C. C. Dow-Hygelund, B. P. Holden, R. J. Bouwens +10
We have obtained a high S/N (22.3 hr integration) UV continuum VLT FORS2 spectrum of an extremely bright (z_850 = 24.3) z = 5.515 +/- 0.003 starforming galaxy (BD38) in the field o…
An X-ray Galaxy Cluster Survey for Investigations of Dark Energy
Z. Haiman, S. Allen, N. Bahcall +34
The amount and nature of dark energy (DE) can be tightly constrained by measuring the spatial correlation features and evolution of a sample of ~ 100,000 galaxy clusters over the r…
Internal dynamics of the z sim 0.8 cluster RX J0152.7-1357
M. Girardi, R. Demarco, P. Rosati +1
We present the results from the dynamical analysis of the cluster of galaxies RX J0152-1357, which shows a complex structure in its X-ray emission, with two major clumps in the cen…
Discovery of an X-ray-Luminous Galaxy Cluster at z=1.4
C. R. Mullis, P. Rosati, G. Lamer +4
We report the discovery of a massive, X-ray-luminous cluster of galaxies at z=1.393, the most distant X-ray-selected cluster found to date. XMMU J2235.3-2557 was serendipitously de…
