Description
We study the synergy of redshift space distortion (RSD) and kinetic Sunyaev Zel’dovich (kSZ) effects from the next stage cosmological surveys in this paper. The next generation of galaxy and CMB surveys are considered, and we compare the behaviors of the traditional slit-based spectroscopic galaxy survey (e.g. DESI) and the slitless spectrosocpic
galaxy survey (CSST as an example). For a more realistic forecast, non-linear models of RSD and kSZ effect are utilized in the Fisher Matrix analyses. The results show that this synergy not only improve out constraints on dark energy and gravity, but also tighten the
uncertainties about our understanding of gas distribution with dark matter halos.
