    Preparing for low surface brightness science with the Vera C. Rubin Observatory: Characterization of tidal features from mock images
    Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure...

    Preparing for LSST data. Estimating the physical properties of z < 2.5 main-sequence galaxies
    Aims: We study how the upcoming Legacy Survey of Space and Time (LSST) data from the Vera C. Rubin Observatory can be employed to constrain the physical...

    Primordial Helium Abundance Determinations
    Based on the best observations of extragalactic H II regions of low metallicity available in the literature we redetermine the primordial helium abundance, Y[p]...
  • Publication
    Principles of supernova-driven winds
    The formation of galaxies is regulated by a balance between the supply of gas and the rate at which it is ejected. Traditional explanations of gas ejection...

    Pristine dwarf galaxy survey - I. A detailed photometric and spectroscopic study of the very metal-poor Draco II satellite
    We present a detailed study of the faint Milky Way satellite Draco II (Dra II) from deep CFHT/MegaCam broad-band g and i photometry and narrow-band metallicity...

    Probing IGM large-scale flows: warps in galaxies at shells of voids
    Context: Hydrodynamical cosmological simulations predict flows of the intergalactic medium along the radial vector of the voids, approximately in the direction...
  • Publication
    Probing nuclear activity versus star formation at z ˜ 0.8 using near-infrared multi-object spectroscopy
    We present near-infrared (NIR) spectroscopic observations of 28 X-ray and mid-infrared selected sources at a median redshift of z ˜ 0.8 in the Extended Groth...

    Probing the Baryon Cycle of Galaxies with SPICA Mid- and Far-Infrared Observations
    The SPICA mid- and far-infrared telescope will address fundamental issues in our understanding of star formation and ISM physics in galaxies. A particular...

    Probing the Dark Matter Radial Profile in Lens Galaxies and the Size of X-Ray Emitting Region in Quasars with Microlensing
    We use X-ray and optical microlensing measurements to study the shape of the dark matter density profile in the lens galaxies and the size of the (soft) X-ray...
