PACT

The pressure of hot gas in groups and clusters galaxies is a key physical quantity, which directly linked to the total mass halo several other thermodynamical properties. In wake previous observational works on distribution massive halos, we have investigated sample 31 detected both Planck Atacama Cosmology Telescope (ACT), MBAC surveys. We made use an optimised Sunyaev-Zeldovich (SZ) map reconstructed from two data sets tailored for detection SZ effect, taking advantage coverage large scales ACT higher spatial resolution. Our average profile covers radial range going 0.04 × R 500 central parts 2.5 outskirts. this way, it improves upon pressure-profile reconstruction based measurements. It compatible, as well competitive, with constraints derived joint X-ray analysis.
