2001ApJ...555L..11M A Measurement of H_0_ from the Sunyaev-Zeldovich Effect Brian S. Mason, Steven T. Myers, and A. C. S. Readhead Received 2000 August 16; accepted 2001 May 9; published 2001 June 27 ABSTRACT We present a determination of the Hubble constant, H_0_, 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 H_0_ = 64_-11_^+14 +/- 14_sys_ km s^-1^ Mpc^-1^ for a standard cold dark matter (CDM) cosmology, or H_0_ = 66_-11_^+14^ +/- 15_sys_ km s^-1^ Mpc^-1^ for a flat {LAMBDA}CDM cosmology. In combination with X-ray cluster measurements and the big bang nucleosynthesis value for {OMEGA}_B_, we find {OMEGA}_M_ = 0.32 +/- 0.05.
