Multiphase observations show molecular gas mass loading factors 10 times higher than ionised gas in ESO 484-036, creating a 3.5 dex discrepancy with cosmological simulations that underpredict cold gas outflows.
TNG50 shows galactic outflow mass loading is non-monotonic with stellar mass, rising rapidly above 10^10.5 Msun due to black hole feedback, and produces fast multi-phase outflows with emergent collimation.

First Results from the TNG50 Simulation: Galactic outflows driven by supernovae and black hole feedback
TNG50 shows galactic outflow mass loading is non-monotonic with stellar mass, rising rapidly above 10^10.5 Msun due to black hole feedback, and produces fast multi-phase outflows with emergent collimation.
