Extended SZ map of the most luminous X-ray cluster, RXJ1347-1145
  We present in this letter a high resolution (22'' FWHM) extended map at 2.1mm of the Sunyaev-Zel'dovich effect toward the most luminous X-ray cluster, RXJ1347-1145. These observations have been performed with the DIABOLO photometer working at the focus of the 30m IRAM radiotelescope. We have derived a projected gas mass of $(1.1 \pm 0.1)\times 10^{14} h_{50}^{-5/2}$M$_{\odot}$ within an angular radius of $\theta=74''$ (ie: projected radius of 0.6Mpc, $H_{0}=50$km/s/Mpc, $\Omega_m=0.3$, $\Omega_\Lambda=0.7$). This result matches very well the expected gas mass from the cluster models of X-ray data. With an unprecedented sensitivity level our measurement does not show significant departure from a spherical distribution. The data analysis also allows us to characterize the 2.1mm flux of a well known radio source lying in the center of the cluster: $F_{RS}(2.1\textrm{mm})=5.7\pm 1.6$mJy.
