Status of Cosmological Parameters

COSMO-97, 1998
The cosmological parameters that I will discuss are the Hubble parameter H 0 ≡100h km s-1 Mpc-1, the age of the universe t 0, the average density Ω0, and the cosmological constant Λ. The most important recent development is the new analyses based on Hipparchos data indicating that the oldest Globular Clusters in our Galaxy have ages of ∼ 11 Gyr.

MEASUREMENT OF COSMOLOGICAL PARAMETERS

Science with the New Generation of High Energy Gamma-Ray Experiments, 2006
The study of the cosmic microwave background (CMB) has played a crucial role in establishing a new standard of precision in the determination of cosmological parameters. The full-sky, high-resolution maps of the CMB recently produced by the WMAP space mission, have reinforced the evidence in favor of a fiat universe, dominated by dark matter and dark ...
