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.
Multi-phase observations of NGC 1427A indicate tidal torquing from a dwarf fly-by has pre-conditioned its gas for ram-pressure stripping by the Fornax intracluster medium, placing the galaxy at the onset of environmental quenching with a declining star formation rate.
Detection of 13-day variability at 100 GHz suggests a Compton-thick AGN in the Antennae galaxies.
Aliphatic side chains on PAHs shift certain infrared band intensity ratios, especially in small molecules, which can mislead ionization-state estimates, though the main diagnostic grid still applies with possible calibration.
Multi-phase molecular gas in IRAS20551-4250 is dominated by cold CO, shows UV-heated warm H2, tidal features from a merger, and no molecular outflows, consistent with ongoing star formation.
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.
