Galaxy evolution in cosmological simulations with outflows - I. Stellar masses and star formation rates: Galaxy evolution in simulations - I. M* and SFR
Open accessAbstract
We examine the growth of the stellar content of galaxies from z= 3 → 0 in cosmological hydrodynamic simulations incorporating parametrized galactic outflows. Without outflows, galaxies overproduce stellar masses (M*) and star formation rates (SFRs) compared to observations. Winds introduce a three-tier form for the galaxy stellar mass and star formation rate functions, where the middle tier depends on the differential (i.e. mass-dependent) recycling of ejected wind material back into galaxies. A tight M*–SFR relation is a generic outcome of all these simulations and its evolution is well described as being powered by cold accretion, although current observations at z≳ 2 suggest that the star formation in small early galaxies must be highly suppressed. Roughly, one-third of z= 0 galaxies at masses below M★ are satellites and the star formation in satellites is not much burstier than in centrals. All models fail to suppress the star formation and stellar mass growth in massive galaxies at z≲ 2, indicating the need for an external quenching mechanism such as black hole feedback. All models also fail to produce dwarfs as young and rapidly star forming as observed. An outflow model following scalings expected for momentum-driven winds broadly matches the observed galaxy evolution around M★ from z= 0 to 3, which is a significant success since these galaxies dominate cosmic star formation, but the failures at higher and lower masses highlight the challenges still faced by this class of models. We argue that central star-forming galaxies are well described as living in a slowly evolving equilibrium between inflows from gravity and recycled winds, star formation, and strong and ubiquitous outflows that regulate how much inflow forms into stars. Star-forming galaxy evolution is thus primarily governed by the continual cycling of baryons between galaxies and intergalactic gas.

“Star formation is modeled using a subgrid recipe introduced in Springel & Hernquist (2003) where a gas particle above a critical density is modeled as a fraction of cold clouds embedded in a warm ionised medium following McKee & Ostriker (1977).”

“This stands in contrast to the canonical model for outflows (e.g. Dekel & Silk 1986) in which outflows escape from small galaxies owing to their small potential wells while being recaptured in large galaxies.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
