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 ...

Cosmology III: The cosmological parameters

2014
In Chap. 4 and 7, we described the fundamental aspects of the standard model of cosmology. Together with the knowledge of galaxies, clusters of galaxies, and AGNs that we have gained in the other chapters, we are now ready to discuss the determination of the various cosmological parameters. In the course of this discussion, we will describe a number of

Beyond Cosmological Parameters

AIP Conference Proceedings, 2003
Observational constraints on spacetime from supernovae Ia, CMB, lensing, Lyman α Forest and galaxy clustering are reviewed, focusing on how the underlying physics (dark matter, dark energy, gravity) can be tested rather than assumed. This is possible because we are simply measuring spacetime, and to 1st order, all observations probe just three ...

Cosmological Parameters: Where are We?

Astrophysics and Space Science, 2004
The present-day large increase of the amount of data relevant to cosmology, as well as their increasing accuracy, leads to the idea that the determination of cosmological parameters has been achieved with a rather good precision, may be of the order of 10%. There is a large consensus around the so-called concordance model. Indeed this model does fit an
