We compare and combine likelihood functions of the cosmolog ical parametersΩm, h and σ8, from peculiar velocities, CMB and type Ia supernovae. Thes e three data sets directly probe the mass in the Universe, without the need to relate the galaxy distribution to the underlying mass via a “biasing” relation. We include the rec ent results from the CMB… CONTINUE READING
