Discovery of Globular Clusters in the Proto-Spiral NGC2915: Implications for Hierarchical Galaxy Evolution
G. R. Meurer, J. P. Blakeslee, M. Sirianni +30
We have discovered three globular clusters beyond the Holmberg radius in Hubble Space Telescope Advanced Camera for Surveys images of the gas-rich dark matter dominated blue compac…
Faint Galaxies in deep ACS observations
N. Benitez, H. Ford, R. Bouwens +33
We present the analysis of the faint galaxy population in the Advanced Camera for Surveys (ACS) Early Release Observation fields VV 29 (UGC 10214) and NGC 4676. Here we attempt to…
Star Formation at z~6: i-dropouts in the ACS GTO fields
R. J. Bouwens, G. D. Illingworth, P. Rosati +33
Using an i-z dropout criterion, we determine the space density of z~6 galaxies from two deep ACS GTO fields with deep optical-IR imaging. A total of 23 objects are found over 46 ar…
Evidence for a Significant Intermediate-Age Population in the M31 Halo from Main Sequence Photometry
Thomas M. Brown, Henry C. Ferguson, Ed Smith +5
We present a color-magnitude diagram (CMD) for a minor-axis field in the halo of the Andromeda galaxy (M31), 51 arcmin (11 kpc) from the nucleus. These observations, taken with the…
HST/ACS Coronagraphic Imaging of the Circumstellar Disk around HD1415659A
M. Clampin, J. E. Krist, D. R. Ardila +31
Multicolor coronagraphic images of the circumstellar disk around HD141569A have been obtained with the Hubble Space Telescope (HST) Advanced Camera for Surveys. B, V, and I images…
Discovery of Two Distant Type Ia Supernovae in the Hubble Deep Field North with the Advanced Camera for Surveys
John P. Blakeslee, Zlatan I. Tsvetanov, Adam G. Riess +30
We present observations of the first two supernovae discovered with the recently installed Advanced Camera for Surveys (ACS) on the Hubble Space Telescope. The supernovae were foun…
Far-Ultraviolet Emission from Elliptical Galaxies at z=0.33
Thomas M. Brown, Henry C. Ferguson, Ed Smith +4
We present far-ultraviolet (far-UV) images of the rich galaxy cluster ZwCl1358.1+6245, taken with the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope (HST)…
Hubble Space Telescope and Ground-Based Optical and Ultraviolet Observations of GRB010222
T. J. Galama, D. Reichart, T. M. Brown +12
We report on Hubble Space Telescope WFPC2 optical and STIS near ultraviolet MAMA observations, and ground-based optical observations of GRB010222, spanning 15 hrs to 71 days. The o…
