A spectroscopic survey of dwarf galaxies in the Coma Cluster: Stellar populations, environment and downsizing
Russell J. Smith, John R. Lucey, Michael J. Hudson +5
We investigate the stellar populations in a sample of 89 faint (M*+2 to M*+4) red galaxies in the Coma cluster, using high S/N spectroscopy from the MMT. Our sample is drawn from t…
A large population of recently-quenched red-sequence dwarf galaxies in the outskirts of the Coma Cluster
Russell J. Smith, Ronald O. Marzke, Ann E. Hornschemeier +6
We analyse the stellar populations of 75 red-sequence dwarf galaxies in the Coma cluster, based on high signal-to-noise spectroscopy from the 6.5m MMT. The sample covers a luminosi…
The HST/ACS Coma Cluster Survey: I - Survey Objectives and Design
David Carter, Paul Goudfrooij, Bahram Mobasher +34
We describe the HST ACS Coma cluster Treasury survey, a deep two-passband imaging survey of one of the nearest rich clusters of galaxies, the Coma cluster (Abell 1656). The survey…
A Compact Cluster of Massive Red Galaxies at a Redshift of 1.51
P. J. McCarthy, H. Yan, R. G. Abraham +15
We describe a compact cluster of massive red galaxies at z=1.51 discovered in one of the Gemini Deep Deep Survey (GDDS) fields. Deep imaging with the Near Infrared Camera and Multi…
Optical and Near-Infrared Observations of the Peculiar Type Ia Supernova 1999ac
Mark M. Phillips, Kevin Krisciunas, Nicholas B. Suntzeff +29
We present 39 nights of optical photometry, 34 nights of infrared photometry, and 4 nights of optical spectroscopy of the Type Ia SN 1999ac. This supernova was discovered two weeks…
Gemini Deep Deep Survey VI: Massive Hdelta-strong galaxies at z=1
Damien Le Borgne, Roberto Abraham, Kathryne Daniel +11
We show that there has been a dramatic decline in the abundance of massive galaxies with strong Hdelta stellar absorption lines from z=1.2 to the present. These ``Hdelta-strong'',…
