Imprints of mass accretion on properties of galaxy clusters
Andreas Faltenbacher, Brandon Allgood, Stefan Gottloeber +2
A large scale SPH+N-body simulation (GADGET) of the concordance LCDM universe is used to investigate orientation and angular momentum of galaxy clusters at z=0 in connection with t…
The Radius of Baryonic Collapse in Disc Galaxy Formation
Susan A. Kassin, Julien Devriendt, S. Michael Fall +3
In the standard picture of disc galaxy formation, baryons and dark matter receive the same tidal torques, and therefore approximately the same initial specific angular momentum. Ho…
The Dependence of Halo Clustering on Halo Formation History, Concentration, and Occupation
Risa H. Wechsler, Andrew R. Zentner, James S. Bullock +2
We investigate the dependence of dark matter halo clustering on halo formation time, density profile concentration, and subhalo occupation number, using high-resolution numerical s…
The Dark Side of the Halo Occupation Distribution
Andrey V. Kravtsov, Andreas A. Berlind, Risa H. Wechsler +4
We analyze the halo occupation distribution (HOD), the probability for a halo of mass M to host a number of subhalos N, and two-point correlation function of galaxy-size dark matte…
The Shape of Galaxy Cluster Dark Matter Haloes: Systematics of Its Imprint on Cluster Gas, and Comparison to Observations
Ricardo A. Flores, Brandon Allgood, Andrey V. Kravtsov +3
(Abridged) We study predictions for galaxy cluster observables that can test the statistics of dark matter halo shapes expected in a flat LCDM universe. We present a simple analyti…
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…
