Planck Early Results XXVI: Detection with Planck and confirmation by XMM-Newton of PLCK G266.6-27.3, an exceptionally X-ray luminous and massive galaxy cluster at z~1
Planck Collaboration, N. Aghanim, M. Arnaud +189
We present first results on PLCK G266.6-27.3, a galaxy cluster candidate detected at a signal-to-noise ratio of 5 in the Planck All Sky survey. An XMM-Newton validation observation…
Planck Early Results: Origin of the submm excess dust emission in the Magellanic Clouds
Planck Collaboration, P. A. R. Ade, N. Aghanim +197
The integrated Spectral Energy Distributions of the Large and Small Magellanic Cloud appear significantly flatter than expected from dust models based on their FIR and radio emissi…
Planck Early Results: The submillimetre properties of a sample of Galactic cold clumps
Planck Collaboration, P. A. R. Ade, N. Aghanim +201
(abridged) We perform a detailed investigation of sources from the Cold Cores Catalogue of Planck Objects (C3PO). Our goal is to probe the reliability of the detections, validate t…
Planck early results: Cluster Sunyaev-Zeldovich optical scaling relations
Planck Collaboration, N. Aghanim, M. Arnaud +202
We present the Sunyaev-Zeldovich (SZ) signal-to-richness scaling relation (Y500-N200) for the MaxBCG cluster catalogue. Employing a multi-frequency matched filter on the Planck sky…
Planck early results. VI. The High Frequency Instrument data processing
Planck HFI Core Team, P. A. R. Ade, N. Aghanim +163
We describe the processing of the 336 billion raw data samples from the High Frequency Instrument (HFI) which we performed to produce six temperature maps from the first 295 days o…
Planck Early Results. X. Statistical analysis of Sunyaev-Zeldovich scaling relations for X-ray galaxy clusters
Planck Collaboration, N. Aghanim, M. Arnaud +197
All-sky data from the Planck survey and the Meta-Catalogue of X-ray detected Clusters of galaxies (MCXC) are combined to investigate the relationship between the thermal Sunyaev-Ze…
Planck Early Results. VII. The Early Release Compact Source Catalog
Planck Collaboration, P. A. R. Ade, N. Aghanim +228
(Abridged) A brief description of the methodology of construction, contents and usage of the Planck Early Release Compact Source Catalogue (ERCSC), including the Early Cold Cores (…
Planck Early Results: Thermal dust in Nearby Molecular Clouds
Planck Collaboration, A. Abergel, P. A. R. Ade +197
Planck allows unbiased mapping of Galactic sub-millimetre and millimetre emission from the most diffuse regions to the densest parts of molecular clouds. We present an early analys…
Planck Early Results XI: Calibration of the local galaxy cluster Sunyaev-Zeldovich scaling relations
Planck Collaboration, P. A. R. Ade, N. Aghanim +207
We present precise Sunyaev-Zeldovich (SZ) effect measurements in the direction of 62 nearby galaxy clusters (z <0.5) detected at high signal-to-noise in the first Planck all-sky da…
Planck Early Results. II. The thermal performance of Planck
Planck Collaboration, P. A. R. Ade, N. Aghanim +225
The performance of the Planck instruments in space is enabled by their low operating temperatures, 20K for LFI and 0.1K for HFI, achieved through a combination of passive radiative…
Planck early results XIV: ERCSC validation and extreme radio sources
Planck Collaboration, P. A. R. Ade, N. Aghanim +206
Planck's all sky surveys at 30-857 GHz provide an unprecedented opportunity to follow the radio spectra of a large sample of extragalactic sources to frequencies 2-20 times higher…
