    ALMA reveals a compact and massive molecular outflow driven by the young AGN in a nearby ULIRG
    The ultraluminous infrared galaxy F13451+1232 is an excellent example of a galaxy merger in the early stages of active galactic nucleus (AGN) activity, a phase...

    ALMA Reveals Potential Evidence for Spiral Arms, Bars, and Rings in High-redshift Submillimeter Galaxies
    We present subkiloparsec-scale mapping of the 870 μm ALMA continuum emission in six luminous (L IR ∼ 5 × 1012 L ⊙) submillimeter galaxies (SMGs) from the ALESS...

    Alone on a wide wide sea. The origin of SECCO 1, an isolated star-forming gas cloud in the Virgo cluster*†‡
    SECCO 1 is an extremely dark, low-mass (M⋆ ≃ 105 M⊙), star-forming stellar system lying in the low-velocity cloud (LVC) substructure of the Virgo cluster of...

    An ALMA survey of CO in submillimetre galaxies: companions, triggering, and the environment in blended sources
    We present ALMA observations of the mid-J 12CO emission from six single-dish selected 870-μm sources in the Extended Chandra Deep Field-South and UKIDSS Ultra...

    An ALMA/NOEMA survey of the molecular gas properties of high-redshift star-forming galaxies
    We have used ALMA and NOEMA to study the molecular gas reservoirs in 61 ALMA-identified submillimetre galaxies (SMGs) in the COSMOS, UDS, and ECDFS fields. We...

    An almost dark galaxy with the mass of the Small Magellanic Cloud
    Almost dark galaxies are objects that have eluded detection by traditional surveys such as the Sloan Digital Sky Survey (SDSS). The low surface brightness of...

    An analysis of STIS HST UV spectra of M 33 early B supergiants
    We present terminal velocities of M 33 B-supergiants, obtained from STIS HST spectra as part of our programme to investigate the Wind Momentum - Luminosity...

    An Empirical Relation between the Large-scale Magnetic Field and the Dynamical Mass in Galaxies
    The origin and evolution of cosmic magnetic fields as well as the influence of the magnetic fields on the evolution of galaxies are unknown. Though not without...

    An ever-present Gaia snail shell triggered by a dark matter wake
    We utilize a novel numerical technique to model star formation in cosmological simulations of galaxy formation - called SUPERSTARS - to simulate a Milky Way...
