    The dark nature of GRB 051022 and its host galaxy
    Aims:We present multiwavelength (X-ray/optical/near-infrared/millimetre) observations of GRB 051022 between 2.5 h and 1.15 yr after the event. It is the most...

    The Dawes Review 10: The impact of deep learning for the analysis of galaxy surveys
    The amount and complexity of data delivered by modern galaxy surveys has been steadily increasing over the past years. New facilities will soon provide imaging...

    The diverse density profiles of galaxy clusters with self-interacting dark matter plus baryons
    We present the first simulated galaxy clusters (M200 > 1014 M⊙) with both self-interacting dark matter (SIDM) and baryonic physics. They exhibit a greater...

    The drop in the cosmic star formation rate below redshift 2 is caused by a change in the mode of gas accretion and by active galactic nucleus feedback
    The cosmic star formation rate is observed to drop sharply after redshift z= 2. We use two large, cosmological, smoothed particle hydrodynamics simulations to...

    The dynamical status of the galaxy cluster Abell 115
    Aims:We present the results of a new spectroscopic and photometric survey of the hot, binary X-ray cluster A115 at z = 0.193, containing a radio relic. Methods...

    The EAGLE simulations of galaxy formation: calibration of subgrid physics and model variations
    We present results from 13 cosmological simulations that explore the parameter space of the `Evolution and Assembly of GaLaxies and their Environments' (EAGLE)...
