EAGLE-Auriga: effects of different subgrid models on the baryon cycle around Milky Way-mass galaxies

Understand

Modern hydrodynamical simulations reproduce many properties of the real universe.

• These simulations model various physical processes, but many of these are included using `subgrid models' due to resolution limits.
• Although different subgrid models have been successful in modelling the effects of supernovae (SNe) feedback on galactic properties, it remains unclear if, and by how much, these differing implementations affect observable halo gas properties.
• In this work, we use `zoom-in' cosmological initial conditions of two volumes selected to resemble the Local Group (LG) evolved with both the Auriga and EAGLE galaxy formation models.
