    Planck intermediate results. X. Physics of the hot gas in the Coma cluster
    We present an analysis of Planck satellite data on the Coma cluster observed via the Sunyaev-Zeldovich effect. Thanks to its great sensitivity, Planck is able...

    Planck intermediate results. XI. The gas content of dark matter halos: the Sunyaev-Zeldovich-stellar mass relation for locally brightest galaxies
    We present the scaling relation between Sunyaev-Zeldovich (SZ) signal and stellar mass for almost 260,000 locally brightest galaxies (LBGs) selected from the...

    Planck intermediate results. XIII. Constraints on peculiar velocities
    Using Planck data combined with the Meta Catalogue of X-ray detected Clusters of galaxies (MCXC), we address the study of peculiar motions by searching for...

    Planck intermediate results. XL. The Sunyaev-Zeldovich signal from the Virgo cluster
    The Virgo cluster is the largest Sunyaev-Zeldovich (SZ) source in the sky, both in terms of angular size and total integrated flux. Planck's wide angular scale...

    Planck intermediate results. XLIII. Spectral energy distribution of dust in clusters of galaxies
    Although infrared (IR) overall dust emission from clusters of galaxies has been statistically detected using data from the Infrared Astronomical Satellite (IRAS...

    Planck intermediate results. XLV. Radio spectra of northern extragalactic radio sources
    Continuum spectra covering centimetre to submillimetre wavelengths are presented for a northern sample of 104 extragalactic radio sources, mainly active...

    Planck intermediate results. XXV. The Andromeda galaxy as seen by Planck
    The Andromeda galaxy (M 31) is one of a few galaxies that has sufficient angular size on the sky to be resolved by the Planck satellite. Planck has detected M...

    Planck intermediate results. XXVI. Optical identification and redshifts of Planck clusters with the RTT150 telescope
    We present the results of approximately three years of observations of Planck Sunyaev-Zeldovich (SZ) sources with the Russian-Turkish 1.5 m telescope (RTT150)...

    Planck intermediate results. XXXIX. The Planck list of high-redshift source candidates
    The Planck mission, thanks to its large frequency range and all-sky coverage, has a unique potential for systematically detecting the brightest, and rarest...
