Description

The NIKA2 camera operating at the IRAM 30-m telescope has unique performance for the resolved observation of the Sunyaev-Zel’dovich effect towards galaxy clusters. As part of the NIKA2 guaranteed-time, the SZ Large Program (LPSZ) is devoted to the high-angular resolution SZ mapping of a representative sample of SZ-selected clusters, at intermediate to high redshift, drawn from the catalogues of the Planck satellite and of the Atacama Cosmology Telescope. Central to this program is the synergy between SZ observations and X-ray data, utilizing measurements from XMM-Newton or Chandra. The main goal of this program is to provide the community with unprecedented measurements of the universal pressure profile and of the scaling law linking the SZ observable to the hydrostatic mass. This effort extends prior studies to encompass higher redshifts and lower mass ranges, aiming to improve the accuracy of cluster cosmology.
I will review the final results concerning: the sample of clusters, the science-ready products (maps, thermodynamic profiles, and integrated quantities), the universal pressure profile and the mass-SZ scaling relation. Cosmological implications of the last two will be presented alongside studies focusing on cluster physics.
