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…
Principal Component Analysis of Galaxy Clustering in Hyperspace of Galaxy Properties
Shuren Zhou, Pengjie Zhang, Ziyang Chen
Ongoing and upcoming galaxy surveys are providing precision measurements of galaxy clustering. However a major obstacle in its cosmological application is the stochasticity in the…
Thermal energy census with the Sunyaev-Zel'dovich effect of DESI galaxy clusters/groups and its implication on the weak lensing power spectrum
Ziyang Chen, Pengjie Zhang, Xiaohu Yang
We carry out a thermal energy census of hot baryons at , by cross-correlating the \emph{Planck} MILCA y-map with 0.8 million clusters/groups selected from the Yang et.al (20…
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…
