An analytic investigation of the scatter in the integrated X-ray properties of galaxy groups and clusters
Michael L. Balogh, Arif Babul, G. Mark Voit +4
(Abridged) We revisit the scaling relationships between the dark matter mass and observed X-ray luminosity and temperature of galaxy clusters and groups in the local Universe. Spec…
Density Profiles of Collisionless Equilibria. I. Spherical Isotropic Systems
Eric I. Barnes, Liliya L. R. Williams, Arif Babul +1
We investigate the connection between collisionless equilibria and the phase-space relation between density and velocity dispersion found in simulations of dark matter halo…
Scalelengths in Dark Matter Halos
E. I. Barnes, L. L. R. Williams, A. Babul +1
We investigate a hypothesis regarding the origin of the scalelength in halos formed in cosmological N-body simulations. This hypothesis can be viewed as an extension of an earlier…
Semi-analytical dark matter halos and the Jeans equation
Crystal G. Austin, Liliya L. R. Williams, Eric I. Barnes +2
Although N-body studies of dark matter halos show that the density profiles, rho(r), are not simple power-laws, the quantity rho/sigma^3, where sigma(r) is the velocity dispersion,…
A Simple and Accurate Model for Intra-Cluster Gas
Jeremiah P. Ostriker, Paul Bode, Arif Babul
Starting with the well-known NFW dark matter halo distribution, we construct a simple polytropic model for the intracluster medium which is in good agreement with high resolution n…
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…
