    Resonantly damped fast MHD kink modes in longitudinally stratified tubes with thick non-uniform transitional layers
    Resonantly damped fast kink quasi-modes are computed in fully resistive magnetohydrodynamics (MHD) for two-dimensional equilibrium models. The equilibrium model...

    Response functions for the inversion of data from unresolved solar magnetic elements.
    By adopting the thin flux tube model as representative of spatially unresolved magnetic elements in the photosphere of the Sun, we identify an adequate set of...

    Retrieval of solar magnetic fields from high-spatial resolution filtergraph data: the Imaging Magnetograph eXperiment (IMaX)
    Context. The design of modern instruments does not only imply thorough studies of instrumental effects but also a good understanding of the scientific analysis...

    Rotating Stars and the Formation of Bipolar Planetary Nebulae. II. Tidal Spin-up
    We present new binary stellar evolution models that include the effects of tidal forces, rotation, and magnetic torques with the goal of testing planetary...

    Sardinia Radio Telescope observations of Abell 194. The intra-cluster magnetic field power spectrum
    Aims: We study the intra-cluster magnetic field in the poor galaxy cluster Abell 194 by complementing radio data, at different frequencies, with data in the...

    Scattering Polarization and Hanle Effect in Stellar Atmospheres with Horizontal Inhomogeneities
    Scattering of light from an anisotropic source produces linear polarization in spectral lines and in the continuum. In the outer layers of a stellar atmosphere...

    Scattering Polarization of Hydrogen Lines in Weakly Magnetized Stellar Atmospheres. I. Formulation and Application to Isothermal Models
    Although the spectral lines of hydrogen contain valuable information on the physical properties of a variety of astrophysical plasmas, including the upper solar...

    Search and analysis of giant radio galaxies with associated nuclei (SAGAN). IV. Interplay with the Supercluster environment
    We investigated the prevalence of giant radio galaxies (GRGs), some of the largest structures powered by supermassive black holes, within supercluster...

    Search for gravitational waves from binary black hole inspirals in LIGO data
    We report on a search for gravitational waves from binary black hole inspirals in the data from the second science run of the LIGO interferometers. The search...
