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…
Galaxies in Southern Bright Star Fields I. Near-infrared imaging
Andrew J. Baker, Richard I. Davies, Matthew D. Lehnert +6
As a prerequisite for cosmological studies using adaptive optics techniques, we have begun to identify and characterize faint sources in the vicinity of bright stars at high Galact…
Observations of HI Absorbing Gas in Compact Radio Sources at Cosmological Redshifts
R. C. Vermeulen, Y. M. Pihlstroem, W. Tschager +12
We present an overview of the occurrence and properties of atomic gas associated with compact radio sources at redshifts up to z=0.85. Searches for HI 21cm absorption were made wit…
Red galaxy overdensities and the varied cluster environments of powerful radio sources with z~1.6
P. N. Best, M. D. Lehnert, G. Miley +1
The environments of a complete subsample of 6 of the most powerful radio-loud AGN at redshifts z~1.6 are investigated, using deep RJK imaging to depths of R~26, J~22.4 and K~20.6.…
