    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...

    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...

    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...
