Statistics of thermal gas pressure as a probe of cosmology and galaxy formation

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Ziyang Chen, Drew Jamieson, Eiichiro Komatsu, Sownak Bose, Klaus Dolag | Summary: 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-Zeldovich effect gives the bias-weighted mean electron pressure, $langle b_mathrm{h}P_erangle$. In […]
