CMBology
Abstract
The details of the CMB power spectrum are being revealed through the combined efforts of the world's CMBologists. The current data set constrains several cosmological parameters. A combination with other (non-lensing) constraints yields estimates of the cosmological constant: OmegaLambda = 0.65 +/- 0.13, the mass density: Omegam = 0.23 +/- 0.08 and the age of the Universe: to = 13.4 +/- 1.6 Gyr. Lensing data is not yet comfortable with these values.
