Descrizione
The abundance of galaxy clusters in mass and redshift is a powerful cosmological probe, that enables the measurement of cosmological parameters in many parts of the electromagnetic spectrum. One of the key elements needed to perform the cosmological exploitation of a cluster survey is the relation between the survey observable and cluster masses. Among these observables, the integrated Compton parameter :math:Y is an observable of Sunyaev-Zeldovich (SZ) surveys, that tightly correlates with the thermal energy content of galaxy clusters, and therefore with their mass.
The relation between the Compton parameter and the mass within $R_{500}$ is one of the goals of the NIKA2 SZ Large Program (LPSZ), also presented in this conference. In this talk, I will present ongoing studies to forecast the constraining power of this LPSZ, using mock simulated datasets that mimic the large program sample, selection function, and typical uncertainties on $Y_{500}$ and $M_{500}$ obtained for analyses of individual clusters.
