Planck Intermediate Results . X . Physics of the hot gas in the Coma cluster


We present an analysis of Planck satellite data on the Coma Cluster observed via the Sunyaev-Zeldovich effect. Thanks to its great sensitivity, Planck is able, for the first time, to detect SZ emission up to r ≈ 3 × R 500. We test previously proposed spherically symmetric models for the pressure distribution in clusters against the azimuthally averaged data… (More)
