New NIR diagnostic diagrams using [C I]/Paγ and H2 1-0 O(5)/PAH 3.3μm ratios correlate with radiation field hardness and distinguish star formation, AGN, and shock excitation in galaxy nuclei.
JWST observations resolve multiphase nuclear and kpc-scale outflows with velocities up to 520 km/s and PAH property gradients in the AGN-starburst composite ULIRG F10565+2448.
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.
Rest-frame 6-8um MIRI luminosity provides broken power-law SFR calibrations with 0.2-0.3 dex scatter and UV+IR composites at 0.15 dex, supporting robust use above log M* ~9 up to z~3.
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.
