    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...
  • Publication
    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...
  • 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...
