    Upper Limit for γ-Ray Emission above 140 GeV from the Dwarf Spheroidal Galaxy Draco
    The nearby dwarf spheroidal galaxy Draco, with its high mass to light ratio, is one of the most auspicious targets for indirect dark matter (DM) searches...

    Using host galaxy spectroscopy to explore systematics in the standardization of Type Ia supernovae
    We use stacked spectra of the host galaxies of photometrically identified Type Ia supernovae (SNe Ia) from the Dark Energy Survey (DES) to search for...

    Very high redshift quasars and the rapid emergence of supermassive black holes
    The observation of quasars at very high redshift such as Pōniuā'ena is a challenge for models of supermassive black hole (SMBH) formation. This work presents a...

    Very Large Telescope-ISAAC Near-Infrared Spectroscopy of ISO-selected Hubble Deep Field South Galaxies
    We report the results of near-infrared Very Large Telescope (VLT)-Infrared Spectrometer and Array Camera (ISAAC) spectroscopy of a sample of 12 galaxies at z=0...

    VLBI imaging of the gravitational lens MG J0414+0534
    We observed the quadruple gravitationally lensed image of MG J0414+0534 on 23 November 1997 with a global VLBI array at 8.4 GHz. We report wide-field imaging...
