JWST difference imaging from COSMOS-Web and PRIMER has yielded 68 high-redshift supernovae including a core-collapse event at z>3 and a Type Ia at z>2, demonstrating the feasibility of wide-area time-domain searches in the early universe.

SN 2025ogs is a spectroscopically normal Type Ia supernova at z=2.05 whose luminosity distance and properties are consistent with low-z standards and current LambdaCDM constraints.
A score-based diffusion generative model on deep infrared galaxy photometry yields a star formation rate density peaking at z=1.3 and shows distinct non-parametric star formation histories plus AGN activity peaking during the quenching transition of massive galaxies.
Stacking analysis shows mean SFR in massive galaxies at 2<z<4.5 declines along the Hubble sequence from ~280 M⊙/yr in irregulars to ~80 M⊙/yr in spheroids, with a simple chemical evolution model explaining the rise in dust-to-stellar mass ratio out to z~8.
PASSAGE releases 2183 spectroscopic redshifts (0.08<z<4.7) from JWST NIRISS observations in COSMOS, with strong agreement to photometric redshifts for multi-line sources and a quantified ~18% misidentification rate for single-line emitters.
Observational analysis of COSMOS galaxy groups shows quiescent fraction builds steadily from z~1.5-2 with faster growth in richer groups, first RS ridgeline galaxies by z~2, a possible early overdensity at z=3.4, and no significant evolution in RS slope or scatter.

COSMOS-Web: Star formation along the early Hubble sequence and the evolution of dust over the redshift range 0<z<12
