Resolved multiphase observations reveal a supernova-driven wind in a z=5.3 galaxy removing gas at twice the star-formation rate, potentially quenching it within 100 Myr and matching local superwind properties.

A new fitting methodology applied to UV absorption data recovers radial trends in galactic wind velocities and mass-loading factors by constraining initial hot and cool phase parameters in a multiphase model.
JWST observations find constant ~1% PAH abundance in the M82 superwind to 5 kpc, consistent with shielding in surface layers of cool clouds and possible replenishment.
Spatially resolved JWST spectroscopy of M82 reveals an average ortho-to-para H2 ratio half the equilibrium value, attributed to short cloud mixing timescales relative to spin conversion and recent rapid heating.
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.
The document records key conclusions, challenges, and open questions from discussion sessions at a 2025 conference focused on interstellar, circumstellar, and galactic dust with emphasis on JWST and ALMA results.
