As cosmic structures form, matter density fluctuations collapse gravitationally and baryonic matter is shock-heated and thermalized.

This value of $B$ is lower than that needed to reconcile the tSZ data with the primordial CMB and CMB lensing data, i. e., $B = 1. 64 \pm 0. 19$, but is consistent with the mass bias expected from hydrodynamical simulations, $B = 1. 28 \pm 0. 20$.

We present a first joint analysis of the power spectra of the thermal Sunyaev-Zeldovich (tSZ) effect measured by the Planck and the number density fluctuations of galaxies in the 2MASS redshift survey (2MRS) catalog, including their cross-correlation.
