On the capability of high redshift kSZ measurement with galaxy surveys
Ziyang Chen, Pengjie Zhang
The kSZ effect has been detected at z<1 using various techniques and data sets. The ongoing and upcoming spectroscopic galaxy surveys such as DESI and PFS will push the detection b…

Detection of pairwise kinetic Sunyaev-Zel'dovich effect with DESI galaxy groups and Planck in Fourier space
Shaohong Li, Yi Zheng, Ziyang Chen +2
We report a detection of the kinetic Sunyaev-Zel'dovich (kSZ) effect in Fourier space, by combining the DESI galaxy groups and the Planck data. We use the density-weight…

Statistics of thermal gas pressure as a probe of cosmology and galaxy formation
Ziyang Chen, Drew Jamieson, Eiichiro Komatsu +8
The statistics of thermal gas pressure are a new and promising probe of cosmology and astrophysics. The large-scale cross-correlation between galaxies and the thermal Sunyaev-Zeldo…
