摘要：The Sunyaev–Zel'dovich (SZ) effect is the distortion of the cosmic microwave background radiation (CMB) through inverse Compton scattering by high energy electrons in hot gas. The peculiar velocity of galaxy cluster could lead to the CMB temperature dispersion due to the kinetic SZ effect. We use Millieum-XXL lightcone mock catalogue to build the full-sky CMB map with kSZ signal. First, we reproduce the detection of Planck CMB temperature dispersion due to kSZ effect from clusters of galaxies. Then, based on the same map construction and statistic methods, we make predictions of kSZ detection S/N for the future CMB experiments (e.g. ACTPol). In addition, we discuss the contribution of subhalo (or satellite galaxy) to the kSZ signal.
