Multi-wavelength data on GRB 260310A support an off-axis jet model explaining weak prompt emission and bright delayed afterglow, including reverse-shock signatures and late X-ray rebrightening.
GRB 250706B/C exhibits temporal features consistent with fallback-regulated accretion operating on a high-luminosity branch in a collapsar.
GRB 260310A/SN 2026fgk is a spectroscopically confirmed Type Ic-BL supernova at z=0.153 with 0.4-0.6 times the luminosity of SN 1998bw, nickel mass 0.4-0.5 solar masses, ejected mass 4-6 solar masses, kinetic energy (3-8) x 10^51 erg, and located at a 15 kpc offset due to the host's extended light p
