Abell 851 and the Role of Starbursts in Cluster Galaxy Evolution
A. Oemler, A. Dressler, D. Kelson +5
We use extensive new observations of the very rich z ~ 0.4 cluster of galaxies A851 to examine the nature and origin of starburst galaxies in intermediate-redshift clusters. New HS…
Morphological Composition of z~0.4 groups: The site of S0 formation
D. J. Wilman, A. Oemler, J. S. Mulchaey +3
The low redshift Universe (z<~0.5) is not a dull place. Processes leading to the suppression of star formation and morphological transformation are prevalent: this is particularly…
Spitzer 24 micron detections of starburst galaxies in Abell 851
A. Dressler, J. Rigby, A. Oemler +4
Spitzer-MIPS 24 micron and ground-based observations of the rich galaxy cluster Abell 851 at z=0.41 are used to derive star formation rates from the mid-IR 24 micron and from [O II…
Unveiling the Important Role of Groups in the Evolution of Massive Galaxies: Insights from an Infrared Passive Sequence at Intermediate Redshift
D. J. Wilman, D. Pierini, K. Tyler +6
The most massive galaxies in the Universe are also the oldest. To overturn this apparent contradiction with hierarchical growth models, we focus on the group scale haloes which hos…
The stellar mass content of distant galaxy groups
Michael L. Balogh, Dave Wilman, Robert D. E. Henderson +8
We have obtained near-infrared imaging of 58 galaxy groups, in the redshift range 0.1<z<0.6, from the William Herschel Telescope and from the Spitzer IRAC data archive. The groups…
The CNOC2 sample of intermediate redshift galaxy groups - the powerhouse of galaxy evolution
D. J. Wilman, M. L. Balogh, R. G. Bower +3
The evolution of galaxies in groups may have important implications for the global evolution of star formation rate in the Universe, since many processes which operate in groups ma…
