New Cosmological Data and the `Best-Fit' FRW Universe

Astrophysics 2017-08-23 v1

Abstract

Observational tests for the homogeneity of the Universe on large scales are reviewed. Assuming the Cosmological Principle we then estimate cosmological parameters by joint analysis of the Cosmic Microwave Background, Supernovae Ia, peculiar velocities, cluster abundance and redshift surveys. Our results are consistent with results obtained by other groups, suggesting a best-fit FRW Universe with \omegam=1λ0.3\omegam = 1 -\lambda \approx 0.3 and H075H_0 \approx 75 km/sec/Mpc. We point out some potential problems with this currently popular model.
