Detection of pairwise kSZ effect with DESI galaxy clusters and Planck
Ziyang Chen, Pengjie Zhang, Xiaohu Yang +1
We report a detection of the pairwise kinematic Sunyaev-Zel'dovich (kSZ) effect, combining galaxy clusters in DESI imaging surveys and the Planck temperature maps. The detecti…
Sensitivity tests of cosmic velocity fields to massive neutrinos
Shuren Zhou, Zhenjie Liu, Qinglin Ma +8
We investigate impacts of massive neutrinos on the cosmic velocity fields, employing high-resolution cosmological -body simulations provided by the information-optimized CUBE co…
Expansion series of the pairwise velocity generating function and its implications on redshift space distortion modeling
Junde Chen, Pengjie Zhang, Yi Zheng
The pairwise velocity generating function has deep connection with both the pairwise velocity probability distribution function and modeling of redshift space distortion (RSD).…
Toward a more stringent test of gravity with redshift space power spectrum: simultaneous probe of growth and amplitude of large-scale structure
Yong-Seon Song, Yi Zheng, Atsushi Taruya
Redshift-space distortions (RSD) offers an exciting opportunity to test the gravity on cosmological scales. In the presence of galaxy bias, however, the RSD measurement at large sc…
