Theoretical challenges in galaxy formation
Naab, Ostriker
In this review, focus on one major challenge for galaxy formation theory: to understand the underlying physical processes that regulate the structure of the interstellar medium, star formation and the driving of galactic outflows. This requires accurate physical models and numerical sims, which can precisely describe the multi-phase structure of the interstellar medium on the currently unresolved few hundred parsecs scales of large scale cosmo sims. Such models ultimately require the full accounting for the dominant cooling and heating processes, the radiation and winds from massive stars and accreting BHs, an accurate treatment of SNe explosions as well as the non-thermal components of the ISM like B fields and cosmic rays.
