Detection of a stellar bar in the extreme gas-rich galaxy GN20 at z=4.055 shows that gas-rich disks support rapid bar formation in the early universe.
JWST MIRI MRS observations show the Galactic Center Minispiral gas has 1-2.5 solar metallicity, Wolf-Rayet driven ionization, significant Ni and Fe dust destruction, and harder radiation in compact structures near Sgr A*.
JWST data reconstructs the inner ejecta of SNR 0540-69.3 as two similar-sized fragmented lobes, implying a ~300 km/s pulsar kick under symmetry assumption and confirming low-velocity hydrogen mixing in a Type II explosion.
Second-epoch JWST/MIRI-MRS mid-IR spectra of SN 1987A show little overall dust evolution but inner equatorial ring fading, rapid ejecta line changes, some ER line fading, first mid-IR H2 from ejecta, and evidence that dense Fe-rich ejecta has reached the reverse shock.
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.
No change detected in ice absorption bands of EC 53 between phases, with ice abundances higher than typical for embedded protostars.
JWST spectra of EC 53 indicate CO fundamental and H2O bending absorption weaken by ~2 during burst due to continuum dilution, with relative veiling yielding hot-continuum ratios of 2.9 and 1.71 and viscous-disk accretion-rate ratios of ~3.6 and ~2.0.
Mid-infrared lines near Sgr A* exhibit no detectable variability during flares, because light-crossing and recombination timescales in the extended gas suppress responses, so the lines cannot constrain instantaneous UV flux.
JWST spectroscopy reveals radio jets in nearby AGN drive multiphase ISM turbulence and shock-dominated H2 excitation both along and perpendicular to the jet direction.
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.
F770W minus F1000W colors below 0.03 mag identify L dwarfs seven times more likely to have silicate clouds, while current models underpredict the 9-micron silicate feature.
