Removing the Impact of Correlated PSF Uncertainties in Weak Lensing
Tianhuan Lu, Jun Zhang, Fuyu Dong +5
Accurate reconstruction of the spatial distributions of the Point Spread Function (PSF) is crucial for high precision cosmic shear measurements. Nevertheless, current methods are n…
An accurate centroid algorithm for PSF reconstruction
Tianhuan Lu, Wentao Luo, Jun Zhang +8
In this work, we present a novel centroiding method based on Fourier space Phase Fitting(FPF) for Point Spread Function(PSF) reconstruction. We generate two sets of simulations to…
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…
