Mass Estimates of X-Ray Clusters
August E. Evrard, Christopher A. Metzler, Julio F. Navarro
We use cosmological gas dynamic simulations to investigate the accuracy of galaxy cluster mass estimates based on X-ray observations. The experiments follow the formation of cluste…
Galaxy Tracers and Velocity Bias
F J Summers, Marc Davis, August E. Evrard
This paper examines several methods of tracing galaxies in N-body simulations and their effects on the derived galaxy statistics, especially measurements of velocity bias. Using tw…
GALAXY DYNAMICS IN CLUSTERS
C. S. Frenk, A. E. Evrard, S. D. M. White +1
We use high resolution simulations to study the formation and distribution of galaxies within a cluster which forms hierarchically. We follow both dark matter and baryonic gas whic…
COSMOLOGICAL CONSTRAINTS FROM CLUSTER X-RAY MORPHOLOGIES
J. J. Mohr, A. E. Evrard, D. G. Fabricant +1
We use a representative sample of 65 galaxy clusters observed with the Einstein IPC to constrain the range of cluster X-ray morphologies. We develop and apply quantitative and repr…
ROSAT Observations of Compact Groups of Galaxies
Rachel A. Pildis, Joel N. Bregman, August E. Evrard
We have systematically analyzed a sample of 13 new and archival ROSAT PSPC observations of compact groups of galaxies: 12 Hickson Compact Groups plus the NCG 2300 group. We find th…
