    Planck early results. XI. Calibration of the local galaxy cluster Sunyaev-Zeldovich scaling relations
    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...
  • Publication
    Planck early results. XII. Cluster Sunyaev-Zeldovich optical scaling relations
    We present the Sunyaev-Zeldovich (SZ) signal-to-richness scaling relation (Y500 - N200) for the MaxBCG cluster catalogue. Employing a multi-frequency matched...
  • Publication
    Planck early results. XIII. Statistical properties of extragalactic radio sources in the Planck Early Release Compact Source Catalogue
    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...
  • Publication
    Planck early results. XIV. ERCSC validation and extreme radio sources
    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...
  • Publication
    Planck early results. XV. Spectral energy distributions and radio continuum spectra of northern extragalactic radio sources
    Spectral energy distributions (SEDs) and radio continuum spectra are presented for a northern sample of 104 extragalactic radio sources, based on the Planck...

    Planck early results. XVI. The Planck view of nearby galaxies
    The all-sky coverage of the Planck Early Release Compact Source Catalogue (ERCSC) provides an unsurpassed survey of galaxies at submillimetre (submm)...
  • Publication
    Planck early results. XVII. Origin of the submillimetre excess dust emission in the Magellanic Clouds
    The integrated spectral energy distributions (SED) of the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) appear significantly flatter than...

    Planck early results. XVIII. The power spectrum of cosmic infrared background anisotropies
    Using Planck maps of six regions of low Galactic dust emission with a total area of about 140 deg2, we determine the angular power spectra of cosmic infrared...

    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
    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...
