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: first assessment of the High Frequency Instrument in-flight performance
Planck HFI Core Team, P. A. R. Ade, N. Aghanim +163
The Planck High Frequency Instrument (HFI) is designed to measure the temperature and polarization anisotropies of the Cosmic Microwave Background and galactic foregrounds in six w…
Planck Early Results: All sky temperature and dust optical depth from Planck and IRAS: Constraints on the "dark gas" in our galaxy
Planck Collaboration, P. A. R. Ade, N. Aghanim +204
We construct an all-sky map of the apparent temperature and optical depth of thermal dust emission using the Planck-HFI and IRAS data. The optical depth maps are correlated to trac…
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…
