    Photospheric downward plasma motions in the quiet Sun
    Context. We analyze spectropolarimetric data taken with the Hinode spacecraft in quiet solar regions at the disk center. Distorted redshifted Stokes V profiles...

    Photospheric magnetic topology of a north polar region
    Aims: We aim to characterise the magnetism of a large fraction of the north polar region close to a maximum of activity, when the polar regions are reversing...

    Physical Properties of Spicules from Simultaneous Spectropolarimetric Observations of He I and Ca II Lines
    We present full Stokes observations from SPINOR (Spectro-Polarimeter for INfrared and Optical Regions, at the Dunn Solar Telescope) in the Ca II infrared...

    Physical Properties of the Solar Magnetic Photosphere under the MISMA Hypothesis. I. Description of the Inversion Procedure
    The paper describes an automatic inversion code to recover microstructured magnetic atmospheres (MISMAs) by fitting Stokes profiles. These solar model...

    Physical Properties of the Solar Magnetic Photosphere under the MISMA Hypothesis. II. Network and Internetwork Fields at the Disk Center
    This paper is the second in a series that models photospheric magnetic structures in terms of atmospheres having optically thin fluctuations of magnetic field...

    Physical Properties of the Solar Magnetic Photosphere under the MISMA Hypothesis. III. Sunspot at Disk Center
    Small-scale fluctuations of magnetic field and velocity may be responsible for the Stokes asymmetries observed in all photospheric magnetic structures (the...

    Planck 2015 results. XIX. Constraints on primordial magnetic fields
    We compute and investigate four types of imprint of a stochastic background of primordial magnetic fields (PMFs) on the cosmic microwave background (CMB)...

    Planck 2018 results. XI. Polarized dust foregrounds
    The study of polarized dust emission has become entwined with the analysis of the cosmic microwave background (CMB) polarization in the quest for the curl-like...

    Planck 2018 results. XII. Galactic astrophysics using polarized dust emission
    Observations of the submillimetre emission from Galactic dust, in both total intensity I and polarization, have received tremendous interest thanks to the...
