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 -- 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…
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-Galaxy Weak Lensing Measurements from SDSS: I. Image Processing and Lensing signals
Wentao Luo, Xiaohu Yang, Jun Zhang +11
As the first paper in a series on the study of the galaxy-galaxy lensing from Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we present our image processing pipeline that corr…
Sussing Merger Trees: Stability and Convergence
Yang Wang, Frazer R. Pearce, Alexander Knebe +15
Merger trees are routinely used to follow the growth and merging history of dark matter haloes and subhaloes in simulations of cosmic structure formation. Srisawat et al. (2013) co…
