The diffuse gamma-ray sky of a Milky Way analogue: Local diversity and global constraints
CR-MHD simulations of a Milky Way analogue reproduce observed gamma-ray luminosities and spectra without tuning, with sky morphology set by local gas density fluctuations and angular power spectra tracing gas column rather than cosmic-ray density.

From short-lived to long-lived clouds: impact of star formation models on giant molecular cloud evolution in simulations of an NGC 300-like galaxy
Star formation model choice in galaxy simulations controls giant molecular cloud lifetimes, yielding 20-30 Myr with sink particles versus over 200 Myr with the gravo-thermo-turbulent prescription.
