Structure in a loitering universe.
(World Scientific Publ Co Pte Ltd, 1992-03-01)
The authors study the formation of structure for a universe that undergoes a recent loitering phase. They compare the nonlinear mass distribution to that in a standard, matter dominated cosmology. The statistical aspects ...
The L-X-T relation and intracluster gas fractions of X-ray clusters
(Blackwell Science Ltd, 1999-05-21)
We re-examine the X-ray luminosity-temperature relation using a nearly homogeneous data set of 24 clusters selected for statistically accurate temperature measurements and absence of strong cooling flows. The data exhibit ...
The Morphology-Density Relation for Galaxies in A Cold Dark Matter-Dominated Universe
(Univ Chicago Press, 1990-12-10)
The Santa Barbara cluster comparison project: A comparison of cosmological hydrodynamics solutions
(Univ Chicago Press, 1999-11-10)
We have simulated the formation of an X-ray cluster in a cold dark matter universe using 12 different codes. The codes span the range of numerical techniques and implementations currently in use, including smoothed particle ...
Galaxy dynamics in clusters
(Univ Chicago Press, 1996-12-01)
We use high-resolution simulations to study the formation and distribution of galaxies within a cluster that forms hierarchically. We follow both dark matter and a gas component that is subject to thermal pressure, shocks, ...
The Contribution of Galaxy Clusters to the Soft-X-Ray Background
(Univ Chicago Press, 1992-05-20)
We examine models for the expected contribution to the X-ray background (XRB) from clusters of galaxies in a flat universe with a spectrum of fluctuations corresponding to the standard cold dark matter picture and for a ...
GRACE: a prototype for the Gran Sasso air Cherenkov experiment
(Elsevier, 1992-10-15)
GRACE is a five element array of air Cherenkov light collectors designed to measure the energy of primary cosmic rays and operate on the terrain over the deep underground muon tracking detector, MACRO, at the Gran Sasso ...
Cosmological simulations with scale-free initial conditions. I. Adiabatic hydrodynamics
(Univ Chicago Press, 1998-08-10)
We analyze hierarchical structure formation based on scale-free initial conditions in an Einstein-de Sitter universe, including a baryonic component with Omega(bary) = 0.05. We present three independent, smoothed particle ...
Formation and Evolution of X-Ray-Clusters - A Hydrodynamic Simulation of the Intracluster Medium
(Univ Chicago Press, 1990-11-10)
