We combine 50, 25, and 12.5 Mpc/h boxes with a quarter billion particles each to show that MUFASA broadly reproduces a wide range of relevant observations, including SFR and specific SFR functions, the mass-metallicity relation, HI and H2 fractions, HI (21 cm) and CO luminosity functions, and cosmic gas density evolution.","authors_text":"Mika H.
