Biased Cold Dark Matter Theory - Trouble from Rich Clusters
(Univ Chicago Press, 1989-06-15)
A Morphology-Cosmology Connection for X-Ray-Clusters
(Univ Chicago Press, 1993-12-10)
We employ N-body/three-dimensional gasdynamic simulations of the formation of galaxy clusters to determine whether cluster X-ray morpholgies can be used as cosmological constraints. Confirming the analytic expectations of ...
The radial velocity dispersion profile of the Galactic halo: constraining the density profile of the dark halo of the Milky Way
(Blackwell Science Ltd, 2005-12)
We have compiled a new sample of 240 halo objects with accurate distance and radial velocity measurements, including globular clusters, satellite galaxies, field blue horizontal branch (FHB) stars and red giant stars from ...
Radio–optical flux behaviour and spectral energy distribution of the intermediate blazar GC 0109+224
(Blackwell Science Ltd, 2004-03)
About 20 years of radio observations of the BL Lac object GC 0109+224 (S2 0109+22, RGB J0112+227) in five bands (from 4.8 to 37 GHz) are presented and analysed together with optical data. Over the past 10 years this blazar ...
Comments on the Bilderberg Continuum Atmosphere
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1968-01)
The Bilderberg Continuum Atmosphere fails to reproduce the observed limb-darkening throughout the range of wavelengths 4500 Å< λ < 25 000 Å. The temperature-pressure diagram for the deep layers of this model is a curve ...
Virialization in N-Body Models of the Expanding Universe: 1. Isolated Pairs
(Univ Chicago Press, 1985)
The intracluster gas fraction in X-ray clusters: constraints on the clustered mass density
(Blackwell Science Ltd, 1997-12-01)
The mean intracluster gas fraction of X-ray clusters within their hydrostatic regions is derived from recent observational compilations of David, Jones & Forman and White & Fabian. At radii encompassing a mean density 500 ...
Evolution of the dark matter phase-space density distributions of ΛCDM haloes
(Blackwell Publishing Ltd, 2009-05-21)
We study the evolution of phase-space density during the hierarchical structure formation of Λ cold dark matter (CDM) haloes. We compute both a spherically averaged surrogate for phase-space density ( Q =Ρ/Σ 3 ) and the ...
