Reminiscences: Exotic Stars and Exotic Elements—An entirely Self-Serving Document
(IOP Publishing Ltd, 2005-01-01)
This article is an expanded version of a talk given at a special session of the ASOS-8 colloquium, celebrating my 70th birthday.
An X-ray size-temperature relation for galaxy clusters: Observation and simulation
(Univ Chicago Press, 1997-12-10)
We show that galaxy clusters conform to a tight relation between X-ray isophotal size R-I and emission-weighted intracluster medium (ICM) temperature [T-X]. The best-fit relation for 41 members of an X-ray flux-limited ...
A Comparison of Cosmological Hydrodynamic Codes
(Univ Chicago Press, 1994-07-20)
We present a detailed comparison of the simulation results of various cosmological hydrodynamic codes. Starting with identical initial conditions based on the cold dark matter scenario for the growth of structure, with ...
Virialization in N-Body Models of the Expanding Universe: 2. All Pairs
(Univ Chicago Press, 1985)
Optical Signatures of High-Redshift Galaxy Clusters
(Univ Chicago Press, 1994-03-20)
We combine an N-body and gasdynamic simulation of structure formation with an updated population synthesis code to explore the expected optical characteristics of a high-redshift cluster of galaxies. We examine a poor (2 ...
Large-Scale Clustering of Galaxies With Massive Dark Halos: 2. Mass-to-Light Profiles and Dynamic Mass Estimates of Galaxy Groups
(Univ Chicago Press, 1987-05-01)
Effects of mergers and core structure on the bulk properties of nearby galaxy clusters
(Univ Chicago Press, 2006-03-01)
We use X-ray morphological measurements and the scatter of clusters about observed and simulated scaling relations to examine the impact of merging and core-related phenomena on the structure of galaxy clusters. We use a ...
Clustering of dark matter halos on the light cone: Scale, time, and mass dependence of the halo biasing in the Hubble volume simulations
(Univ Chicago Press, 2001-11-10)
We develop a phenomenological model to predict the clustering of dark matter halos on the light cone by combining several existing theoretical models. Assuming that the velocity field of halos on large scales is approximated ...
Measuring the Mean and Scatter of the X-Ray Luminosity-Optical Richness Relation for maxBCG Galaxy Clusters
(Univ Chicago Press, 2007-03-01)
Determining the scaling relations between galaxy cluster observables requires large samples of uniformly observed clusters. We measure the mean X-ray luminosity-optical richness (L¯X-N¯200) relation for an approximately ...
