The nature of damped HI absorbers probed by cosmological simulations: satellite accretion and outflows

Nils Henrik Pehlivan Rhodin, Oscar Agertz, Lise Christensen +2

We use state-of-the-art cosmological zoom simulations to explore the distribution of neutral gas in and around galaxies that gives rise to high column density \ion{H}{i} \mbox{Ly-$…
