    • The low-redshift circumgalactic medium in SIMBA 

      Appleby, Sarah; Dave´, Romeel; Sorini, Daniele; Storey-Fisher, Kate; Smith, Britton (Oxford University Press, 2021-08)
      We examine the properties of the low-redshift circumgalactic medium (CGM) around star-forming and quenched galaxies in the SIMBA cosmological hydrodynamic simulations, focusing on comparing H I and metal line absorption ...

    • Lyman α absorption beyond the disc of simulated spiral galaxies 

      Dave´, Romeel; Rottgers, Bernhard; Naab, Thorsten (Oxford University Press, 2020)
      We present an analysis of the origin and properties of the circumgalactic medium (CGM) in a suite of 11 cosmological zoom simulations resembling present-day spiral galaxies. On average the galaxies retain about 50 per cent ...

    • MAMMOTH: Confirmation of two massive galaxy overdensities at z = 2.24 with Hα emitters 

      An, F.X; Zheng, X.Z; Cai, Z (Oxford University Press, 2021)
      Massive galaxy overdensities at the peak epoch of cosmic star formation provide ideal testbeds for the formation theories of galaxies and large-scale structure. We report the confirmation of two massive galaxy overdensities ...

    • Testing galaxy formation simulations with damped Lyman-α abundance and metallicity evolution 

      Hassan, Sultan; Finlator, Kristian; Dave, Romeel (Oxford University Press, 2020)
      We examine the properties of damped Lyman-α absorbers (DLAs) emerging from a single set of cosmological initial conditions in two state-of-the-art cosmological hydrodynamic simulations: SIMBA and TECHNICOLOR DAWN. The ...
