Halo Asymmetry in the Modeling of Galaxy Clustering

The Astrophysical Journal
Conventional studies of galaxy clustering within the framework of halo models typically assume that the density profile of all dark matter halos can be approximated by the Navarro–Frenk–White (NFW) spherically symmetric profile.

Linking Warm Dark Matter to Merger Tree Histories via Deep Learning Networks

The Astrophysical Journal
Dark matter (DM) halos form hierarchically in the Universe through a series of merger events. By pairing halo finder and postprocessing codes, merger series in cosmological simulations can be conveniently represented as a graph-like “tree” structure ...

The Formation of Dark Matter Halos and High-Redshift Galaxies

, 2011
In the concordance LCDM cosmological model, galaxies form in the centers of dark matter halos and merge with one another following the mergers of their host halos. Thus, we set out to quantify the growth mechanisms of dark matter halos. For this purpose, we analyze several large N-body simulations of the growth of cosmic structure.
