    An Empirical Relation between the Large-scale Magnetic Field and the Dynamical Mass in Galaxies
    The origin and evolution of cosmic magnetic fields as well as the influence of the magnetic fields on the evolution of galaxies are unknown. Though not without...
  • Publication
    An open-source, massively parallel code for non-LTE synthesis and inversion of spectral lines and Zeeman-induced Stokes profiles
    With the advent of a new generation of solar telescopes and instrumentation, interpreting chromospheric observations (in particular, spectropolarimetry)...
  • Publication
    An uncombed inversion of multiwavelength observations reproducing the net circular polarization in a sunspot's penumbra
    Context. The penumbra of sunspots has a complex magnetic field topology whose three-dimensional organization remains unclear after more than a century of...
  • Publication
    An Upper Limit on the Temporal Variations of the Solar Interior Stratification
    We have analyzed changes in the acoustic oscillation eigenfrequencies measured over the past 7 years by the GONG, MDI, and LOWL instruments. The observations...

    Analyse multi-echelle des champs magnetiques dans des nuages moleculaires a structures filamentaires
    Together with other observational methods, visible and near infra-red polarimetry can help to understand the morphology of magnetic fields in the neighborhood...
  • Publication
    Analysis of a spatially deconvolved solar pore
    Solar pores are active regions with large magnetic field strengths and apparent simple magnetic configurations. Their properties resemble the ones found for the...
  • Publication
    Analysis of Quiet-Sun Internetwork Magnetic Fields Based on Linear Polarization Signals
    We present results from the analysis of Fe I 630 nm measurements of the quiet Sun taken with the spectropolarimeter of the Hinode satellite. Two data sets with...
  • Publication
    Analytic Approximate Seismology of Propagating Magnetohydrodynamic Waves in the Solar Corona
    Observations show that propagating magnetohydrodynamic (MHD) waves are ubiquitous in the solar atmosphere. The technique of MHD seismology uses the wave...
  • Publication
    Analytic approximate seismology of transversely oscillating coronal loops
    Aims: We present an analytic approximate seismic inversion scheme for damped transverse coronal loop oscillations based on the thin tube and thin boundary...
