Dependence of halo properties on central-satellite magnitude gaps through weak lensing measurements
Mingtao Yang, Jiaxin Han, Wenting Wang +9
The magnitude gap between the central and satellite galaxies encodes information about the mass accretion history of a dark matter halo, and serves as a useful observational probe…
Full-sky ray-tracing simulation of weak lensing using ELUCID simulations: exploring galaxy intrinsic alignment and cosmic shear correlations
Chengliang Wei, Guoliang Li, Xi Kang +15
The intrinsic alignment of galaxies is an important systematic effect in weak-lensing surveys, which can affect the derived cosmological parameters. One direct way to distinguish d…
Mapping the Real Space Distributions of Galaxies in SDSS DR7: II. Measuring the growth rate, clustering amplitude of matter and biases of galaxies at redshift
Feng Shi, Xiaohu Yang, Huiyuan Wang +9
We extend the real-space mapping method developed in Shi et at. (2016) so that it can be applied to flux-limited galaxy samples. We use an ensemble of mock catalogs to demonstrate…
Mapping the real space distributions of galaxies in SDSS DR7: I. Two Point Correlation Functions
Feng Shi, Xiaohu Yang, Huiyuan Wang +8
Using a method to correct redshift space distortion (RSD) for individual galaxies, we mapped the real space distributions of galaxies in the Sloan Digital Sky Survey (SDSS) Data Re…
Using member galaxy luminosities as halo mass proxies of galaxy groups
Yi Lu, Xiaohu Yang, Shiyin Shen
Reliable halo mass estimation for a given galaxy system plays an important role both in cosmology and galaxy formation studies. Here we set out to find the way that can improve the…
Constraining the Star Formation Histories in Dark Matter Halos: I. Central Galaxies
Xiaohu Yang, H. J. Mo, Frank C. van den Bosch +5
Using the self-consistent modeling of the conditional stellar mass functions across cosmic time by Yang et al. (2012), we make model predictions for the star formation histories (S…
Log-Poisson Non-Gaussianity of Ly Transmitted Flux Fluctuations at High Redshift
Yi Lu, Weishan Zhu, Yaoquan Chu +2
We investigate the non-Gaussian features of the IGM at redshift using Ly transmitted flux of quasar absorption spectra and cosmological hydrodynamic simulation of…
