Evolution of Dark Matter Phase-Space Density Distributions in Equal-Mass Halo Mergers
Ileana M. Vass, Stelios Kazantzidis, Monica Valluri +1
We use dissipationless N-body simulations to investigate the evolution of the true coarse-grained phase-space density distribution f(x,v) in equal-mass mergers between dark matter…
Cold Dark Matter Substructure and Galactic Disks I: Morphological Signatures of Hierarchical Satellite Accretion
Stelios Kazantzidis, James S. Bullock, Andrew R. Zentner +2
(Abridged) We conduct a series of high-resolution, dissipationless N-body simulations to investigate the cumulative effect of substructure mergers onto thin disk galaxies in the co…
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…
The Robustness of Dark Matter Density Profiles in Dissipationless Mergers
Stelios Kazantzidis, Andrew R. Zentner, Andrey V. Kravtsov
We present a comprehensive series of dissipationless N-body simulations to investigate the evolution of density distribution in equal-mass mergers between dark matter (DM) halos an…
