Abstract

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 Angls-Alczar et al. (2017a) 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 10 3 km s -1 at high Eddington ratios, increasing to 8000 km s -1 at Eddington ratios below 2%, with a constant momentum input of 20L/c. Simba further includes an on-the-fly dust production,…
