The Dependence of Dark Matter Halo Properties on the Morphology of Their Central Galaxies from Weak Lensing

The Astrophysical Journal
Xu & Jing reported a monotonic relationship between the host halo mass M _h and the morphology of massive central galaxies, characterized by the Sérsic index n , at fixed stellar mass, suggesting that morphology could serve as a good secondary proxy for ...

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.

Constructing a Galaxy Cluster Catalog in IllustrisTNG300 Using the Mulguisin Algorithm

The Astrophysical Journal
We present a new simulated galaxy cluster catalog based on the IllustrisTNG simulation. We use the Mulguisin (MGS) algorithm to identify galaxy overdensities.

Origin and Full Characterization of the Secondary (Assembly) Halo Bias

The Astrophysical Journal
The clustering of dark matter halos depends not only on their mass, the so-called primary bias, but also on their internal properties, the so-called secondary bias.

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.
