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…
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…
ELUCID -- Exploring the Local Universe with the reConstructed Initial Density field. II: Reconstruction diagnostics, applied to numerical halo catalogs
Dylan Tweed, Xiaohu Yang, Huiyuan Wang +5
The ELUCID project aims to build a series of realistic cosmological simulations that reproduce the spatial and mass distribution of the galaxies as observed in the Sloan Digital Sk…
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…
ELUCID - Exploring the Local Universe with reConstructed Initial Density field III: Constrained Simulation in the SDSS Volume
Huiyuan Wang, H. J. Mo, Xiaohu Yang +7
A method we developed recently for the reconstruction of the initial density field in the nearby Universe is applied to the Sloan Digital Sky Survey Data Release 7. A high-resoluti…
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…
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…
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…
