Mind the Gap: from Plasma Kinetics to Cosmological Galaxy Formation
In the modern picture of galaxy formation, baryonic feedback is critical for shaping galaxies and regulating star formation. On small scales, feedback results from transporting momentum, radiation, thermal and relativistic particles but current-day magneto-hydrodynamic simulations of galaxies and galaxy clusters often neglect or over-simplify these transport processes. Electrons transport heat and cosmic rays exchange momentum and energy with the thermal plasma but both species are erroneously assumed to diffuse along magnetic field lines. However, this is in conflict with the latest plasma simulations and observations in the solar wind and of the galactic center, which imply efficient…
