Planck intermediate results: I. Further validation of new Planck clusters with XMM-Newton
We present further results from the ongoing XMM-Newton validation follow-up of Planck cluster candidates, detailing X-ray observations of eleven candidates detected at a signal-to-noise ratio of 4.5 < S/N < 5.3 in the same 10-month survey maps used in the construction of the Early SZ sample. T...

| description |
We present further results from the ongoing XMM-Newton validation follow-up of Planck cluster candidates, detailing X-ray observations of eleven candidates detected at a signal-to-noise ratio of 4.5 < S/N < 5.3 in the same 10-month survey maps used in the construction of the Early SZ sample. The sample was selected in order to test internal SZ quality flags, and the pertinence of these flags is discussed in light of the validation results. Ten of the candidates are found to be bona fide clusters lying below the RASS flux limit. Redshift estimates are available for all confirmed systems via X-ray Fe-line spectroscopy. They lie in the redshift range 0.19 < z < 0.94, demonstrating Planck's capability to detect clusters up to high z. The X-ray properties of the new clusters appear to be similar to previous new detections by Planck at lower z and higher SZ flux: the majority are X-ray underluminous for their mass, estimated using Yx as mass proxy, and many have a disturbed morphology. We find tentative indication for Malmquist bias in the Ysz-Yx relation, with a turnover at Ysz~4x 10-4 arcmin2. We present additional new optical redshift determinations with ENO and ESO telescopes of candidates previously confirmed with XMM-Newton. The X-ray and optical redshifts for a total of 20 clusters are found to be in excellent agreement. We also show that useful lower limits can be put on cluster redshifts using X-ray data only via the use of the Yx vs. Ysz and X-ray flux Fx vs. Ysz relations. |

The present work is based on ob- servations obtained with XMM-Newton, an ESA science mission with instru- ments and contributions directly funded by ESA Member States and the USA (NASA), on observations made with the IAC80 telescope operated on the is- land of Tenerife by the Instituto de Astrofsica de Canarias in the Spanish Observatorio del Teide and on observations collected using the ESO/MPG 2.2 m telescope on La Silla under MPG programs 086.A-9001 and 087.A- 9003. This research has made use of the following databases: SIMBAD, op- erated at the CDS, Strasbourg, France; the NED database, which is operated by the Jet Propulsion Laboratory, California Institute of Technology, under con- tract with the National Aeronautics and Space Administration; BAX, which is operated by the Laboratoire d’Astrophysique de Tarbes-Toulouse (LATT), un- der contract with the Centre National d’Études Spatiales (CNES); and the SZ repository operated by IAS Data and Operation centre (IDOC) under contract with CNES.
