Cosmological parameters from pre-planck cosmic microwave background measurements

Abstract:

Recent data from the WMAP, ACT and SPT experiments provide precise measurements of the cosmic microwave background temperature power spectrum over a wide range of angular scales. The combination of these observations is well fit by the standard, spatially flat ΛCDM cosmological model, constraining six free parameters to within a few percent. The scalar spectral index, n s=0.9690±0.0089, is less than unity at the 3.5σ level, consistent with simple models of inflation. The damping tail of the p...
