    The bifurcated age-metallicity relation of Milky Way globular clusters and its implications for the accretion history of the galaxy
    We use recently derived ages for 61 Milky Way (MW) globular clusters (GCs) to show that their age-metallicity relation (AMR) can be divided into two distinct...
  • Publication
    The bivariate gas-stellar mass distributions and the mass functions of early- and late-type galaxies at z {∼} 0
    We report the bivariate $HI$ - and $H 2$ -stellar mass distributions of local galaxies in addition of an inventory of galaxy mass functions, MFs, for $HI$ , $H...

    The black hole population in low-mass galaxies in large-scale cosmological simulations
    Recent systematic searches for massive black holes (BHs) in local dwarf galaxies led to the discovery of a population of faint active galactic nuclei (AGNs). We...

    The Blazar TXS 0506+056 Associated with a High-energy Neutrino: Insights into Extragalactic Jets and Cosmic-Ray Acceleration
    A neutrino with energy ˜290 TeV, IceCube-170922A, was detected in coincidence with the BL Lac object TXS 0506+056 during enhanced gamma-ray activity, with...

    The BOSS Emission-line Lens Survey. IV. Smooth Lens Models for the BELLS GALLERY Sample
    We present Hubble Space Telescope F606W-band imaging observations of 21 galaxy-Lyα emitter lens candidates in the Baryon Oscillation Spectroscopic Survey...

    The bright end of the luminosity function at z ~ 9
    Context. We present additional constraints on the galaxy luminosity function at z ~ 9 based on observations carried out with ESO/VLT FORS2, HAWK-I, and X...

    The bright extragalactic ALMA redshift survey (BEARS) - II. Millimetre photometry of gravitational lens candidates
    We present 101- and 151-GHz ALMA continuum images for 85 fields selected from Herschel observations that have 500-μm flux densities >80 mJy and 250-500-μm...
