    The nuclear ring in the unbarred galaxy NGC 278: Result of a minor merger?
    We present fully sampled high angular resolution two-dimensional kinematics in the Hα spectral line, optical and near-infrared imaging, as well as 21 cm atomic...
  • Publication
    The nuclear starburst activity in the Seyfert 2 galaxy NGC 7679
    We present our recent spectrophotometric results of the infrared luminous Seyfert 2 galaxy NGC 7679. We find compelling evidence for the presence of a recent...

    The nuclear stellar disc of the Milky Way: A dynamically cool and metal-rich component possibly formed from the central molecular zone
    Context. The nuclear stellar disc (NSD) is, together with the nuclear star cluster (NSC) and the central massive black hole, one of the main components in the...
  • Publication
    The nucleus of NGC 253 and its massive stellar clusters at parsec scales
    Very Large Telescope adaptive optics images of NGC 253 with resolutions down to 200mas resolve the central 300pc of this galaxy in ~37 infrared (IR) bright...

    The Number of Dwarf Satellites of Disk Galaxies versus their Bulge Mass in the Standard Model of Cosmology
    There is a correlation between the bulge mass of the three main galaxies of the Local Group (LG), i.e., M31, Milky Way (MW), and M33, and the number of their...
  • Publication
    The number of globular clusters around the iconic UDG DF44 is as expected for dwarf galaxies
    There is a growing consensus that the vast majority of ultradiffuse galaxies (UDGs) are dwarf galaxies. However, there remain a few UDGs that seem to be special...

    The Number of Tidal Dwarf Satellite Galaxies in Dependence of Bulge Index
    We show that a significant correlation (up to 5σ) emerges between the bulge index, defined to be larger for a larger bulge/disk ratio, in spiral galaxies with...
  • Publication
    The O3N2 and N2 abundance indicators revisited: improved calibrations based on CALIFA and Te-based literature data
    The use of integral field spectroscopy is since recently allowing to measure the emission line fluxes of an increasingly large number of star-forming galaxies...
  • Publication
    The obliquity and atmosphere of the hot Jupiter WASP-122b (KELT-14b) with ESPRESSO: An aligned orbit and no sign of atomic or molecular absorption
    Thanks to their short orbital periods and hot extended atmospheres, hot Jupiters are ideal candidates for atmosphere studies with high- resolution spectroscopy...
