    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...

    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...

    The spectral energy distribution of the central parsecs of the nearest AGN
    Spectral energy distributions (SEDs) of the central few tens of parsec region of some of the nearest, most well-studied, active galactic nuclei (AGN) are...

    The Spectral Evolution of the First Galaxies. III. Simulated James Webb Space Telescope Spectra of Reionization-epoch Galaxies with Lyman-continuum Leakage
    Using four different suites of cosmological simulations, we generate synthetic spectra for galaxies with different Lyman-continuum escape fractions (f esc) at...
  • Publication
    The spectral index-flux density relation for extragalactic radio sources selected at metre and decametre wavelengths
    We use the recent releases of sensitive VLA/LOFAR large-area surveys at 340 MHz and 54 MHz, in conjunction with the 1.4 GHz NVSS, to accurately determine the...
