    Aperture corrections for disk galaxy properties derived from the CALIFA survey. Balmer emission lines in spiral galaxies
    This work investigates the effect of the aperture size on derived galaxy properties for which we have spatially-resolved optical spectra. We focus on some...
  • Publication
    Applicability of Milne-Eddington inversions to high spatial resolution observations of the quiet Sun
    Context. The physical conditions of the solar photosphere change on very small spatial scales both horizontally and vertically. Such a complexity may pose a...
  • Publication
    Application of speckle and (multi-object) multi-frame blind deconvolution techniques on imaging and imaging spectropolarimetric data
    Context. Ground-based imaging and imaging spectropolarimetric data are often subjected to post-facto reconstruction techniques to improve the spatial resolution...
  • Publication
    Application of the Eddington inversion method to constrain the dark matter halo of galaxies using only observed surface brightness profiles
    Context. The halos of low-mass galaxies may allow us to constrain the nature of dark matter (DM), but the kinematic measurements needed to diagnose the required...

    Approximate Bayesian neural Doppler imaging
    Aims: The non-uniform surface temperature distribution of rotating active stars is routinely mapped with the Doppler imaging technique. Inhomogeneities in the...

    Are beryllium abundances anomalous in stars with giant planets?
    In this paper we present beryllium (Be) abundances in a large sample of 41 extra-solar planet host stars, and for 29 stars without any known planetary-mass...

    Are collisions with neutral hydrogen important for modeling the second solar spectrum of Ti I and Ca II?
    Context: The physical interpretation of scattering line polarization offers a novel diagnostic window for exploring the thermal and magnetic structure of the...

    Are early-type galaxies quenched by present-day environment?: A study of dwarfs in the Fornax Cluster
    Galaxies undergo numerous transformative processes throughout their lifetimes that ultimately lead to the expulsion of gas and the cessation of star-forming...

    Are high polarization quasars and BL Lacertae objects really different? A study of the optical spectral properties.
    The continuum and emission lines properties of a sample of 73 blazars is studied, investigating differences and similarities among normal low-polarization...
