ELUCID V. Lighting dark matter halos with galaxies
Xiaohu Yang, Youcai Zhang, Huiyuan Wang +16
In a recent study, using the distribution of galaxies in the north galactic pole of SDSS DR7 region enclosed in a 500$\mpch$ box, we carried out our ELUCID simulation (Wang et al.…
ELUCID IV: Galaxy Quenching and its Relation to Halo Mass, Environment, and Assembly Bias
Huiyuan Wang, H. J. Mo, Sihan Chen +17
We examine the quenched fraction of central and satellite galaxies as a function of galaxy stellar mass, halo mass, and the matter density of their large scale environment. Matter…
Revealing the cosmic web dependent halo bias
Xiaohu Yang, Youcai Zhang, Tianhuan Lu +7
Halo bias is the one of the key ingredients of the halo models. It was shown at a given redshift to be only dependent, to the first order, on the halo mass. In this study, four typ…
Galaxy groups in the 2MASS Redshift Survey
Yi Lu, Xiaohu Yang, Feng Shi +6
A galaxy group catalog is constructed from the 2MASS Redshift Survey (2MRS) with the use of a halo-based group finder. The halo mass associated with a group is estimated using a `G…
An empirical model to form and evolve galaxies in dark matter halos
Shijie Li, Youcai Zhang, Xiaohu Yang +8
Based on the star formation histories (SFH) of galaxies in halos of different masses, we develop an empirical model to grow galaxies in dark mattet halos. This model has very few i…
