Dark Matter Halos: Assembly, Clustering and Sub-halo Accretion
Dark matter Galaxy formation Halos
2014/12/9
I carried out systematic studies on the assembly history of dark matter halos, using numerical simulations and semi-analytical methods. First, I look into dark halo mass assembly history. I confirmed ...
Pairwise Velocities of Dark Matter Halos: a Test for the Lambda Cold Dark Matter Model using the Bullet Cluster
method : N-body simulations — galaxies : evolution — galaxies : for-mation — galaxies: clusters — cosmology : theory — cosmology : dark matter
2011/10/13
The existence of a bullet cluster (such as 1E0657-56) poses a challenge to the concordance Lambda cold dark matter model. Here we investigate the velocity distribution of dark matter halo pairs in lar...
Statistical mechanics of collisionless orbits. I. Origin of central cusps in dark-matter halos
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Statistical Mechanics (cond-mat.stat-mech)
2010/12/23
We present an equilibrium statistical mechanical theory of collisionless self-gravitational systems with isotropic velocity distributions.
Evidence Against Dark Matter Halos Surrounding the Globular Clusters MGC1 and NGC 2419
Dark Matter Halos Surrounding the Globular Clusters MGC1 NGC 2419
2011/1/11
The conjecture that the ancient globular clusters (GCs) formed at the center of their own dark matter halos was first proposed by Peebles (1984), and has recently been revived to explain the puzzling ...
Cores and Cusps in Warm Dark Matter Halos
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
The apparent presence of large core radii in Low Surface Brightness galaxies has been claimed as evidence in favor of warm dark matter. Here we show that WDM halos do not have cores that are large fra...
Dark Matter Halos: The Dynamical Basis of Effective Empirical Models
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/29
We investigate the dynamical basis of the classic empirical models (specifically, Sersic-Einasto and generalized NFW) that are widely used to describe the distributions of collisionless matter in gala...
