    The Spatial Distribution of the Far-Infrared Emission in NGC 253
    We study the far-infrared emission properties of the nearby starburst galaxy NGC 253 based on IRAS maps and an ISOPHOT map at 180 μm. Based on the analysis of...

    The spatial extent of polycyclic aromatic hydrocarbons emission in the Herbig star HD 179218
    Aim. We investigate, in the mid-infrared, the spatial properties of the polycyclic aromatic hydrocarbons (PAHs) emission in the disk of HD 179218, an...
  • Publication
    The spatially extended LINERs NGC 4579 and 6500
    Narrow-band Hα+[NII] imaging and long-slit spectroscopy at intermediate resolution from [NeV] lambda3426 to [SIII] lambda9532 of the LINER galaxies NGC 4579 and...
  • Publication
    The spatially resolved broad line region of IRAS 09149-6206
    We present new near-infrared VLTI/GRAVITY interferometric spectra that spatially resolve the broad Brγ emission line in the nucleus of the active galaxy IRAS...

    The spectra of IceCube Neutrino (SIN) candidate sources - III. Optical spectroscopy and source characterization of the full sample
    A correlation between astrophysical high-energy neutrinos and blazars has been suggested by various authors. In particular, a likely association between IceCube...
  • Publication
    The spectra of IceCube neutrino candidate sources - I. Optical spectroscopy of blazars
    There is mounting evidence that ultra-energetic neutrinos of astrophysical origin may be associated with blazars. Here, we investigate a unique sample of 47...

    The spectra of late type dwarfs and sub-dwarfs in the near ultraviolet. II - Limits to variability in MgII emission from IUE spectrophotometry
    The chromospheric h and k emission cores of the G dwarfs and subdwarfs Beta Hyi (14), Zeta Tuc (5), Delta Pav (5), and Tau Cet (5) have been monitored over a...
  • Publication
    The spectra of late-type dwarfs and sub-dwarfs in the near ultraviolet. I - Line identifications
    Spectra from IUE of 6 main sequence and near main sequence stars from classes A5 to G8, between 2700 A and 2900 A wavelength are described. In toto, some 250...
  • Publication
    The spectra of late-type dwarfs and sub-dwarfs in the near ultraviolet. III - an atlas of MG II H and K profiles
    Using a radically new suite of data extraction routines, IUEARM, high resolution IUE spectra of six F and G stars, taken at regular intervals since 1978 are...
