    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...

    Planck intermediate results. XXXVI. Optical identification and redshifts of Planck SZ sources with telescopes at the Canary Islands observatories
    We present the results of approximately three years of observations of Planck Sunyaev-Zeldovich (SZ) sources with telescopes at the Canary Islands observatories...

    Planck intermediate results. XXXVII. Evidence of unbound gas from the kinetic Sunyaev-Zeldovich effect
    By looking at the kinetic Sunyaev-Zeldovich effect (kSZ) in Planck nominal mission data, we present a significant detection of baryons participating in large...
