The Evolution of Galaxies in X-ray Luminous Groups
Tesla E. Jeltema, John S. Mulchaey, Lori M. Lubin +1
We investigate the galaxy populations in seven X-ray selected, intermediate-redshift groups (0.2<z<0.6). Overall, the galaxy populations in these systems are similar to those in cl…
X-ray Properties of Intermediate-Redshift Groups of Galaxies
T. E. Jeltema, J. S. Mulchaey, L. M. Lubin +2
We have undertaken a multiwavelength project to study the relatively unknown properties of groups and poor clusters of galaxies at intermediate redshifts. In this paper, we describ…
X-ray Selected Intermediate-Redshift Groups of Galaxies
John S. Mulchaey, Lori M. Lubin, Chris Fassnacht +2
We present spectroscopic confirmation of nine moderate redshift galaxy groups and poor clusters selected from the ROSAT Deep Cluster Survey. The groups span the redshift range z=0.…
The Gravitational Lens -- Galaxy Group Connection. II. Groups Associated with B2319+051 and B1600+434
M. W. Auger, C. D. Fassnacht, A. L. Abrahamse +2
We report on the results of a spectroscopic survey of the environments of the gravitational lens systems CLASS B1600+434 (z_l = 0.41, z_s = 1.59) and CLASS B2319+051 (z_l = 0.62).…
