Studying Dark Energy with Galaxy Cluster Surveys
Joseph J. Mohr, Brian OShea, August E. Evrard +2
Galaxy cluster surveys provide a powerful means of studying the density and nature of the dark energy. The redshift distribution of detected clusters in a deep, large solid angle S…
Importance of Cluster Structural Evolution in Using X-ray and SZE Galaxy Cluster Surveys to Study Dark Energy
Subhabrata Majumdar, Joseph J. Mohr
We examine the prospects for measuring the dark energy equation of state parameter w within the context of the still uncertain redshift evolution of galaxy cluster structure. We sh…
Cosmological Implications of the BIMA 30 Ghz Sunyaev-Zel'dovich Effect Galaxy Cluster Survey
Yen-Ting Lin, Joseph J. Mohr
We explore the cosmological implications of 7 deep survey fields observed at the Berkeley-Illinois-Maryland Association (BIMA) Array with 30 GHz receivers. These observations probe…
Redshift of Galaxy Clusters from the Sunyaev-Zel'dovich effect
J. M Diego, J. Mohr, J. Silk +1
We develop a new method for estimating the redshift of galaxy clusters through resolved images of the Sunyaev-Zel'dovich effect (SZE). Our method is based on morphological observab…
A Cold Front in a Preheated Galaxy Cluster
John J. Bialek, August E. Evrard, Joseph J. Mohr
We present a simulated cluster of galaxies, modeled with a pre-heated intracluster medium, that exhibits X-ray features similar to the `cold fronts' seen in Chandra observations. M…
Mass Profile of the Infall Region of the Abell 2199 Supercluster
K. Rines, M. J. Geller, A. Diaferio +3
Using a redshift survey of 1323 galaxies (1092 new or remeasured) in a region of 95 square degrees centered on the nearby galaxy cluster Abell 2199, we analyze the supercluster con…
