JWST MIRI observations of 634 galaxies at 0.2<z<2 yield IR luminosity functions with faint-end slope α≈0.147, implying lower dust-obscured SFRD than previous ALMA/Herschel/Spitzer studies.
The ionization parameter inferred from O32 rises with redshift and sSFR, falls with stellar mass, and increases by ~4x from z=2 to z=6 at fixed mass and sSFR, with a ~0.3 dex model systematic.
JWST data show massive quiescent galaxies in high-redshift proto-clusters formed and quenched simultaneously, with AGN signatures, indicating environmental triggering of quenching.
EP250905a is best explained as a mildly off-axis structured-jet afterglow at z=2.714, possibly weakly magnified by a foreground galaxy at z=0.374.
Clumpy galaxies at cosmic noon show systematically lower metallicities than the mass-metallicity relation, with clump properties indicating metal-poor gas accretion as the driver rather than mergers.
SN 2025ngs is a short-plateau supernova resembling SN 1998S but fainter, with spectral evidence for interaction with a proximate ring-like circumstellar medium around a supergiant progenitor.
The PINK updates enhance the CELEBI FRB pipeline with better astrometry, time-frequency gating, polarization calibration, DM optimization tools, and a software container for improved efficiency and localization of events like FRB 20251019A.
