Status of Cosmology
Abstract
The cosmological parameters that I will emphasize are the Hubble parameter H0 100 h km s-1 Mpc-1, the age of the universe t0, the average matter density Ωm, the baryonic matter density Ωb, the neutrino density Ων, and the cosmological constant ΩΛ. The evidence currently favors t0 ≈ 13 Gyr, h ≈ 0.65, Ωm ≈ 0.3, ΩΛ≈ 0.7.
