Super-Kamiokande's SNWATCH system now delivers supernova direction alerts in about 90 seconds via a new fast HEALPix fitter and an upgraded maximum-likelihood fitter that incorporates gadolinium data.
NEFERTITI simulations show that the Milky Way's most metal-poor stars largely come from a handful of accreted massive dwarf galaxies, while reproducing the JWST Hebe galaxy at z~11 as a pure Population III system.
Simulations indicate the Vera C. Rubin Observatory can optimally localize nearly all observable galactic supernova neutrino triggers and has a 57-97% chance of catching the optical supernova.
