The frequency of very young galaxies in the local Universe: I. A test for galaxy formation and cosmological models
Dylan P. Tweed, Gary A. Mamon, Trinh X. Thuan +5
In the local Universe, the existence of very young galaxies (VYGs), having formed at least half their stellar mass in the last 1 Gyr, is debated. We predict the present-day fractio…
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 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…
