Wide-Field Chandra X-Ray Observations of AGN in Abell 85 & Abell 754
Gregory R. Sivakoff, Paul Martini, Ann I. Zabludoff +2
To better understand the mechanism or mechanisms that lead to AGN activity today, we measure the X-ray AGN fraction in a new sample of nearby clusters and examine how it varies wit…
The Evolution of the Field and Cluster Morphology-Density Relation for Mass-Selected Samples of Galaxies
A. van der Wel, B. P. Holden, M. Franx +7
The Sloan Digital Sky Survey (SDSS) and photometric/spectroscopic surveys in the GOODS-South field (the Chandra Deep Field-South, CDFS) are used to construct volume-limited, stella…
Mass-Selection and the Evolution of the Morphology-Density Relation from z=0.8 to z=0
B. P. Holden, G. D. Illingworth, M. Franx +11
We examined the morphology-density relations for galaxy samples selected by luminosity and by mass in each of five massive X-ray clusters from z=0.023 to 0.83 for 674 spectroscopic…
The Distribution of AGN in Clusters of Galaxies
Paul Martini, John S. Mulchaey, Daniel D. Kelson
We present a study of the distribution of AGN in clusters of galaxies with a uniformly selected, spectroscopically complete sample of 35 AGN in eight clusters at z = 0.06 to 0.31.…
Line Strengths in Early-Type Cluster Galaxies at z=0.33: Implications for alpha/Fe, Nitrogen and the Histories of E/S0s
Daniel D. Kelson, Garth D. Illingworth, Marijn Franx +1
[Heavily Abbreviated] In this paper we analyze previously published spectra with high signal-to-noise ratios of E/S0 galaxies in the rich cluster CL1358+62 at z=0.33, and introduce…
