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…
Advanced Camera for Surveys Photometry of the Cluster RDCS1252.9-2927: The Color-Magnitude Relation at z=1.24
J. P. Blakeslee, M. Franx, M. Postman +20
We investigate the color-magnitude (CM) relation of galaxies in the distant X-ray selected cluster RDCS1252.9-2927 at z=1.24 using images obtained with the Advanced Camera for Surv…
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…
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…
