simba: Cosmological simulations with black hole growth and feedback
Open accessAbstract
We introduce the simba simulations, the next generation of the mufasa cosmological galaxy formation simulations run with gizmo’s meshless finite mass hydrodynamics. simba includes updates to mufasa’s sub-resolution star formation and feedback prescriptions, and introduces black hole growth via the torque-limited accretion model of Anglés-Alcázar et al. from cold gas and Bondi accretion from hot gas, along with black hole feedback via kinetic bipolar outflows and X-ray energy. Ejection velocities are taken to be |${\sim } 10^3\,\,{\rm km}\, {\rm s}^{-1}$| at high Eddington ratios, increasing to |${\sim } 8000\,\,{\rm km}\, {\rm s}^{-1}$| at Eddington ratios below 2 per cent, with a constant momentum input of 20L/c. simba further includes an on-the-fly dust production, growth, and destruction model. Our simba run with |$(100h^{-1}\, {\rm Mpc})^3$| and 10243 gas elements reproduces numerous observables, including galaxy stellar mass functions at z = 0−6, the stellar mass–star formation rate main sequence, H i and H2 fractions, the mass–metallicity relation at z ≈ 0, 2, star-forming galaxy sizes, hot gas fractions in massive haloes, and z = 0 galaxy dust properties. However, simba also yields an insufficiently sharp truncation of the z = 0 mass function, and too-large sizes for low-mass quenched galaxies. We show that simba’s jet feedback is primarily responsible for quenching massive 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.
