A simulation study finds that a hot gas halo at galaxy total mass ~10^12.5 solar masses suppresses cool gas accretion, driving a redshift-independent turnover in the stellar-to-total mass ratio via reduced in-situ star formation efficiency.
Simulations demonstrate that high-specific-energy supernova outflows sustain hot CGM at virial temperature, raise t_cool/t_ff above 10, and transition dwarf galaxy feedback from ejective to preventive mode around 5 Gyr.

How High-Specific-Energy Winds Regulate the Circumgalactic Medium of Dwarf Galaxies
Simulations demonstrate that high-specific-energy supernova outflows sustain hot CGM at virial temperature, raise t_cool/t_ff above 10, and transition dwarf galaxy feedback from ejective to preventive mode around 5 Gyr.
