    Planck intermediate results. XXII. Frequency dependence of thermal emission from Galactic dust in intensity and polarization<xref ref-type="fn" rid="FN1">
    Planck has mapped the intensity and polarization of the sky at microwave frequencies with unprecedented sensitivity. We use these data to characterize the...

    Planck intermediate results. XXIII. Galactic plane emission components derived from Planck with ancillary data
    Planck data when combined with ancillary data provide a unique opportunity to separate the diffuse emission components of the inner Galaxy. The purpose of the...

    Planck intermediate results. XXIV. Constraints on variations in fundamental constants
    Any variation in the fundamental physical constants, more particularly in the fine structure constant, α, or in the mass of the electron, me, affects the...

    Planck intermediate results. XXIX. All-sky dust modelling with Planck, IRAS, and WISE observations
    We present all-sky modelling of the high resolution Planck, IRAS, and WISE infrared (IR) observations using the physical dust model presented by Draine & Li in...

    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. XXVIII. Interstellar gas and dust in the Chamaeleon clouds as seen by Fermi LAT and Planck
    The nearby Chamaeleon clouds have been observed in γ rays by the Fermi Large Area Telescope (LAT) and in thermal dust emission by Planck and IRAS. Cosmic rays...

    Planck intermediate results. XXX. The angular power spectrum of polarized dust emission at intermediate and high Galactic latitudes
    The polarized thermal emission from diffuse Galactic dust is the main foreground present in measurements of the polarization of the cosmic microwave background...

    Planck intermediate results. XXXII. The relative orientation between the magnetic field and structures traced by interstellar dust
    The role of the magnetic field in the formation of the filamentary structures observed in the interstellar medium (ISM) is a debated topic owing to the paucity...
