Abstract: The environment within dark matter haloes can quench the star formation of galaxies. However, environmental effects beyond the virial radius of haloes (≳ 1 Mpc) are less evident. An example is the debated correlation between… read more here.

DOI: 10.1093/mnras/stx2138
Abstract: We have explored the outskirts of dark matter haloes out to 2.5 times the virial radius using a large sample of halos drawn from Illustris, along with a set of zoom simulations (MUGS). Using these,… read more here.
