Ω0 and λ0 from galaxy and quasar clustering: cosmic virial theorem and cosmological redshift-space distortion
Yasushi Suto
Abstract
I discuss two cosmological tests to determine the cosmological density parameter Ω0 the cosmological constant λ0, which make use of the anisotropy of the two-point correlation functions due to the peculiar velocity field and the cosmological redshift-space distortion.
