Description
I will review the evolution of observations of the Sunyaev-Zeldovich (SZ) signal from groups and clusters of galaxies within the course of the past two decades. The SZ effect has become an efficient way to investigate the astrophysics of the hot intra-cluster gas, very competitive and complementary to X-ray observations, and thereby renew the use of massive halos as a cosmological probe. I will discuss the SZ observational and theoretical progress in the perspective of the NIKA2 observations of galaxy clusters.
