    The NIR Ca ii triplet at low metallicity. Searching for extremely low-metallicity stars in classical dwarf galaxies
    The NIR Ca ii triplet absorption lines have proven to be an important tool for quantitative spectroscopy of individual red giant branch stars in the Local Group...

    The NOEMA observations of GN-z11: constraining the neutral interstellar medium and dust formation in the heart of cosmic reionization at z = 10.6
    We present results of dust continuum and [C II]$\, 158\, {\rm \mu m}$ emission line observations of a remarkably UV luminous (M UV = -21.6) galaxy at z = 10.603...

    The nuclear activity and central structure of the elliptical galaxy NGC 5322
    We have analysed a new high-resolution e-MERLIN 1.5 GHz radio continuum map together with HST and SDSS imaging of NGC 5322, an elliptical galaxy hosting radio...
  • Publication
    The nuclear and extended infrared emission of the Seyfert galaxy NGC 2992 and the interacting system Arp 245
    We present subarcsecond resolution infrared (IR) imaging and mid-IR (MIR) spectroscopic observations of the Seyfert 1.9 galaxy NGC 2992, obtained with the...
  • Publication
    The nuclear and extended mid-infrared emission of Seyfert galaxies
    We present subarcsecond resolution mid-infrared (MIR) images obtained with 8-10 m-class ground-based telescopes of a complete volume-limited (DL 40 Mpc) sample...
  • Publication
    The nuclear and integrated far-infrared emission of nearby Seyfert galaxies
    We present far-infrared (FIR) 70-500 μm imaging observations obtained with Herschel/Photodetector Array Camera (PACS) and Spectral and Photometric Imaging...
  • Publication
    The nuclear dust lane of Circinus: collimation without a torus
    In some AGN, nuclear dust lanes connected to kpc-scale dust structures provide all the extinction required to obscure the nucleus, challenging the role of the...
  • Publication
    The Nuclear Infrared Emission of Low-luminosity Active Galactic Nuclei
    We present high-resolution mid-infrared (MIR) imaging, nuclear spectral energy distributions (SEDs), and archival Spitzer spectra for 22 low-luminosity active...
  • Publication
    The Nuclear Near-Infrared Spectral Properties of Nearby Galaxies
    We present spectra of the nuclear regions of 50 nearby (D = 1-92 Mpc, median = 20 Mpc) galaxies of morphological types E to Sm. The spectra, obtained with the...
