    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 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...

    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...

    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 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...

    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...
