Scientific paper

We report the detection of the Sunyaev-Zel'dovich effect in the Coma cluster of galaxies with the 5.5 m telescope at the Owens Valley Radio Observatory. The measured decrement of the temperature of the cosmic microwave background is Delta T0,obs = -270 +/- 29 mu K. After correcting for the effect of discrete radio sources and applying current models for the X-ray atmosphere of the cluster, we calculate the peak of the effect to be Delta T0(0) = -505 +/- 92 mu K. Using the same X-ray models, and assuming spherical symmetry for the gas atmosphere, we derive a Hubble constant of H0 = 71^{+30}_{-25} km s-1 Mpc-1. This is the first detection of the Sunyaev-Zel'dovich effect in a nearby cluster of galaxies.
