Abstract (from CDS):

We present first results on PLCKG266.6-27.3, a galaxy cluster candidate detected at a signal-to-noise ratio of 5 in the Planck All Sky survey. An XMM-Newton validation observation has allowed us to confirm that the candidate is a bona fide galaxy cluster. With these X-ray data we measure an accurate redshift, z=0.94±0.02, and estimate the cluster mass to be M500=(7.8±0.8)x1014M☉. PLCKG266.6-27.3 is an exceptional system: its luminosity of LX[0.5-2.0keV]=(1.4±0.05)x1045erg/s equals that of the two most luminous known clusters in the z > 0.5 universe, and it is one of the most massive clusters at z∼1. Moreover, unlike the majority of high-redshift clusters, PLCKG266.6-27.3 appears to be highly relaxed. This observation confirms Planck's capability of detecting high-redshift, high-mass clusters, and opens the way to the systematic study of population evolution in the exponential tail of the mass function.
