    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...
