Resolving the thermal component of stellar feedback with the"anchor-and-refine"scheme in galactic simulations
(abridged) Stellar feedback regulates galactic baryon cycles, but galaxy-scale simulations often cannot resolve supernova cooling radii. Momentum-based subgrid models can consequently underresolve the hot gas around young stars. We develop an"anchor-and-refine"feedback scheme that anchors a host cell near each star par...
