Abstract (from CDS):

We present a determination of the Hubble constant, H0, from measurements of the Sunyaev-Zeldovich effect in an orientation-unbiased sample of seven z<0.1 galaxy clusters. With improved X-ray models and a more accurate 32 GHz calibration, we obtain H0=64+14–11±14sys km.s–1.Mpc–1 for a standard cold dark matter (CDM) cosmology, or H0=66+14–11±15sys km.s–1.Mpc–1 for a flat ΛCDM cosmology. In combination with X-ray cluster measurements and the big bang nucleosynthesis value for ΩB, we find ΩM=0.32±0.05.
