76 N/O-enhanced galaxies at 4<z<8.5 are observed shortly after starbursts, either in the WR enrichment phase within 10 Myr or the AGB phase after 30-40 Myr following outflows.

A new redshift-correlation technique with third-generation GW detectors can constrain the BNS contribution to cosmic r-process nucleosynthesis to 5-6% precision via Fisher forecasts on mock bright- and dark-siren data.
Stellar streams encode the initial mass function of globular clusters, recovered as a declining power-law with slope 1.3 for streams above 1000 solar masses.
High-resolution mapping reveals nitrogen enrichment around super star clusters in NGC 5253, attributed to Wolf-Rayet stars with material expelled to surrounding gas.
Measures a new nebular attenuation curve from 1400-9550 Å for galaxy GOODSN-17940 at z=4.41 that is steeper than Milky Way/SMC/Calzetti at long wavelengths, similar in blue-optical, and shallower in UV with no 2175 Å bump.
JWST spectra reveal that two z~7 galaxies already show near-solar iron-to-silicon ratios with no strong odd-even effect, favoring early Type Ia supernovae over pair-instability supernovae as the source of iron enrichment.
LRDs require Compton-thick gas at moderate metallicity plus high accretion rates producing weak X-rays to explain their non-detection, implying they are not chemically pristine.
ALMA maps reveal offset compact CO clouds with subthermal excitation in Mrk 996, yielding a molecular gas mass of a few 10^7 solar masses and evidence for a substantial CO-dark H2 component.
N-body models of young and old dense star clusters show BBH mergers span primary masses from ~6 to >100 solar masses with a peak near 8 solar masses, reproducing the LIGO-inferred distribution, with low-mass mergers mostly from metal-rich clusters.
