Constraining the optical depth of galaxies and velocity bias with cross-correlation between kinetic Sunyaev-Zeldovich effect and peculiar velocity field

Yin-Zhe Ma, Guo-Dong Gong, Ning Sui +1

We calculate the cross-correlation function $⟨(\Delta T/T)(\mathbf{v}\cdot \mathbf{n}/{\sigma }_v)⟩$ between the kinetic Sunyaev-Zeldovich (kSZ) effect and the reconstructed pecu…
