    The Intriguing Stellar Populations in the Globular Clusters NGC 6388 and NGC 6441
    NGC 6388 and NGC 6441 are two massive Galactic bulge globular clusters that share many properties, including the presence of an extended horizontal branch (HB)...
  • Publication
    The ionised and molecular mass of post-common-envelope planetary nebulae. The missing mass problem
    Context. Most planetary nebulae (PNe) show beautiful, axisymmetric morphologies despite their progenitor stars being essentially spherical. Close binarity is...
  • Publication
    The ionized gas at the centre of IC 10: a possible localized chemical pollution by Wolf-Rayet stars
    We present results from integral field spectroscopy with the Potsdam Multi-Aperture Spectrograph at the 3.5-m telescope at Calar Alto Observatory of the intense...
  • Publication
    The ionizing radiation from massive stars and its impact on HII regions: results from modern model atmospheres
    We present a detailed comparison of the ionizing spectral energy distributions (SEDs) predicted by four modern stellar atmosphere codes, TLUSTY, CMFGEN, WM...
  • Publication
    The ISLAandS Project II: The Lifetime Star-formation Histories of Six Andomeda DSPHS
    The Initial Star formation and Lifetimes of Andromeda Satellites (ISLAndS) project employs Hubble Space Telescope imaging to study a representative sample of...
  • Publication
    The ISLAnds Project. III. Variable Stars in Six Andromeda Dwarf Spheroidal Galaxies
    We present a census of variable stars in six M31 dwarf spheroidal satellites observed with the Hubble Space Telescope. We detect 870 RR Lyrae (RRL) stars in the...
  • Publication
    The kinematic behaviour of optical recombination lines and collisionally excited lines in Galactic planetary nebulae*†
    The kinematics of the plasma in 14 planetary nebulae (PNe) is analysed by measuring the expansion velocities (Vexp) of different ions as derived from their...

    The Large Magellanic Cloud as a laboratory for hot bottom burning in massive asymptotic giant branch stars
    We use Spitzer observations of the rich population of asymptotic giant branch (AGB) stars in the Large Magellanic Cloud (LMC) to test models describing the...
  • Publication
    The Large Magellanic Cloud stellar content with SMASH. I. Assessing the stability of the Magellanic spiral arms
    The Large Magellanic Cloud (LMC) is the closest and most studied example of an irregular galaxy. Among its principal defining morphological features, its off...
