Study on the mapping of halo clustering from real space to redshift space
Yi Zheng, Yong-Seon Song, Minji Oh
The mapping of galaxy clustering from real space to redshift space introduces the anisotropic property to the measured galaxy density power spectrum in redshift space, known as the…

Accurate determination of halo velocity bias in simulations and its cosmological implications
Junde Chen, Pengjie Zhang, Yi Zheng +2
A long-standing issue in peculiar velocity cosmology is whether the halo/galaxy velocity bias at large scale. The resolution of this important issue must resort to high pre…

Hybrid modeling of redshift space distortions
Yong-Seon Song, Yi Zheng, Atsushi Taruya +1
The observed power spectrum in redshift space appears distorted due to the peculiar motion of galaxies, known as redshift-space distortions (RSD). While all the effects in RSD are…
