Application of a Self-Similar Pressure Profile to Sunyaev-Zel'dovich Effect Data from Galaxy Clusters
T. Mroczkowski, M. Bonamente, J. E. Carlstrom +16
We investigate the utility of a new, self-similar pressure profile for fitting Sunyaev-Zel'dovich (SZ) effect observations of galaxy clusters. Current SZ imaging instruments - such…
Effects of Galaxy Formation on Thermodynamics of the Intracluster Medium
Daisuke Nagai, Andrey V. Kravtsov, Alexey Vikhlinin
We present detailed comparisons of the intracluster medium (ICM) in cosmological Eulerian cluster simulations with deep Chandra observations of nearby relaxed clusters. To assess t…
The Impact of Baryonic Cooling on Giant Arc Abundances
Eduardo Rozo, Daisuke Nagai, Charles Keeton +1
Using ray tracing for simple analytic profiles, we demonstrate that the lensing cross section for producing giant arcs has distinct contributions due to arcs formed through image d…
Testing X-ray Measurements of Galaxy Clusters with Cosmological Simulations
Daisuke Nagai, Alexey Vikhlinin, Andrey V. Kravtsov
X-ray observations of galaxy clusters potentially provide powerful cosmological probes if systematics due to our incomplete knowledge of the intracluster medium (ICM) physics are u…
Effects of cooling and star formation on the baryon fractions in clusters
Andrey V. Kravtsov, Daisuke Nagai, Alexey A. Vikhlinin
We study the effects of dissipation on the baryon fractions in clusters using high-resolution cosmological simulations of nine clusters that resolve formation of cluster galaxies.…
The Radial Distribution of Galaxies in LCDM clusters
Daisuke Nagai, Andrey V. Kravtsov
We study the radial distribution of subhalos and galaxies using high-resolution cosmological simulations of galaxy clusters formed in the concordance LCDM cosmology. In agreement w…
Response of dark matter halos to condensation of baryons: cosmological simulations and improved adiabatic contraction model
Oleg Y. Gnedin, Andrey V. Kravtsov, Anatoly A. Klypin +1
The cooling of gas in the centers of dark matter halos is expected to lead to a more concentrated dark matter distribution. The response of dark matter to the condensation of baryo…
The Effect of Gas Cooling on the Shapes of Dark Matter Halos
Stelios Kazantzidis, Andrey V. Kravtsov, Andrew R. Zentner +3
We analyze the effect of dissipation on the shapes of dark matter (DM) halos using high-resolution cosmological gasdynamics simulations of clusters and galaxies in the LCDM cosmolo…
