Planck Intermediate Results. I. Further validation of new Planck clusters with XMM-Newton
The Planck Collaboration, N. Aghanim, M. Arnaud +182
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-…
Planck Early Results: Statistical properties of extragalactic radio sources in the Planck Early Release Compact Source Catalogue
Planck Collaboration, P. A. R. Ade, N. Aghanim +201
The data reported in Planck's Early Release Compact Source Catalogue (ERCSC) are exploited to measure the number counts (dN/dS) of extragalactic radio sources at 30, 44, 70, 100, 1…
Planck Early Results: The Planck View of Nearby Galaxies
Planck Collaboration, P. A. R. Ade, N. Aghanim +192
The all-sky coverage of the Planck Early Release Compact Source Catalogue (ERCSC) provides an unsurpassed survey of galaxies at submillimetre (submm) wavelengths, representing a ma…
Planck Early Results: The Galactic Cold Core Population revealed by the first all-sky survey
Planck Collaboration, P. A. R. Ade, N. Aghanim +202
We present the statistical properties of the first version of the Cold Core Catalogue of Planck Objects (C3PO), in terms of their spatial distribution, temperature, distance, mass,…
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. XV. Spectral energy distributions and radio continuum spectra of northern extragalactic radio sources
Planck Collaboration, J. Aatrokoski, P. A. R. Ade +246
Spectral energy distributions (SEDs) and radio continuum spectra are presented for a northern sample of 104 extragalactic radio sources, based on the Planck Early Release Compact S…
Planck Early Results. V. The Low Frequency Instrument data processing
A. Zacchei, D. Maino, C. Baccigalupi +146
We describe the processing of data from the Low Frequency Instrument (LFI) used in production of the Planck Early Release Compact Source Catalogue (ERCSC). In particular, we discus…
Planck Early Results XVIII: The power spectrum of cosmic infrared background anisotropies
Planck Collaboration, P. A. R. Ade, N. Aghanim +202
Using Planck maps of six regions of low Galactic dust emission with a total area of about 140 square degrees, we determine the angular power spectra of cosmic infrared background (…
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. IX. XMM-Newton follow-up for validation of Planck cluster candidates
Planck Collaboration, N. Aghanim, M. Arnaud +197
We present the XMM-Newton follow-up for confirmation of Planck cluster candidates. Twenty-five candidates have been observed to date using snapshot (~10 ksec) exposures, ten as par…
Planck Early Results VIII: The all-sky Early Sunyaev-Zeldovich cluster sample
Planck Collaboration, P. A. R. Ade, N. Aghanim +235
We present the first all-sky sample of galaxy clusters detected blindly by the Planck satellite through the Sunyaev-Zeldovich (SZ) effect from its six highest frequencies. This ear…
