The Effects of Radiative Cooling on the Entropy Distribution of Intracluster Gas
Ian G. McCarthy, Mark A. Fardal, Arif Babul
High resolution X-ray observations indicate that the entropy profiles in the central regions of some massive cooling flow clusters are well approximated by powerlaws. McCarthy and…
The phase-space density distribution of dark matter halos
Liliya L. R. Williams, Crystal Austin, Eric Barnes +2
High resolution N-body simulations have all but converged on a common empirical form for the shape of the density profiles of halos, but the full understanding of the underlying ph…
The Satellite-substructure Connection
James E. Taylor, Arif Babul, Joseph Silk
We describe our recent attempts to model substructure in dark matter halos down to very small masses, using a semi-analytic model of halo formation. The results suggest that numeri…
New Tests of the Cluster Entropy Floor Hypothesis
Ian G. McCarthy, Arif Babul, Michael L. Balogh +1
Recent efforts to account for the observed X-ray luminosity - temperature relation of galaxy clusters has led to suggestions that the ICM has an apparent ``entropy floor'' at or ab…
A Semi-analytic Model of Halo Dynamics
James E. Taylor, Arif Babul
We have developed a new semi-analytic model for the formation and evolution of structure on galaxy, group and cluster scales. The model combines merger trees with a detailed, spati…
Statistics of Gravitational Microlensing Magnification. II. Three-Dimensional Lens Distribution
Man Hoi Lee, Arif Babul, Lev Kofman +1
In Paper I we studied the theory of gravitational microlensing for a planar distribution of point masses. In this second paper, we extend the analysis to a three-dimensional lens d…
