    COLDz: A High Space Density of Massive Dusty Starburst Galaxies ∼1 Billion Years after the Big Bang
    We report the detection of CO(J = 2 → 1) emission from three massive dusty starburst galaxies at z > 5 through molecular line scans in the NSF's Karl G. Jansky...

    Compact Galaxies and Super Massive Black Holes
    Most massive galaxies have supermassive black holes at their centres, and the masses of the black holes correlate with properties of the host-galaxy bulge...

    COSMOS-Web: Unraveling the Evolution of Galaxy Size and Related Properties at 2 < z < 10
    We measure galaxy sizes from 2 < z < 10 using COSMOS-Web, the largest-area JWST imaging survey to date, covering ∼0.54 deg 2. We analyze the rest-frame optical...

    Dark matter in early-type galaxies: a SAURON view
    From galaxy formation theory we expect galaxies to be embedded in massive dark matter haloes. For spiral and dwarf galaxies this has indeed been observationally...

    Dark matter in galaxies
    The distribution of matter in galaxies of different luminosities and Hubble types, as inferred from observations, plays an important role in cosmology...
