Synthetic observables from tECSN models show slower early red-color decline due to higher Ti/Cr and a late-time 12.8 μm Ne II line that strengthens over time, unlike comparable CO deflagration models.

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.
KamLAND finds 7 events consistent with background in 9+ kton-year exposure using NN classification and sets 90% CL DSNB flux upper limits of 38-43 cm^{-2} s^{-1} plus model-independent antineutrino flux bounds below 13.3 MeV.
Simulations show the low-T/|W| instability develops robustly across five nuclear EOS in a rapidly rotating 35 M⊙ progenitor, with dominant GW frequency correlating to PNS compactness and stiffness.
sntools has been updated with pre-supernova neutrino support, including time-binning optimizations and ongoing validation for Hyper-Kamiokande use.
