Structured GRB jet simulations find that local electron cooling shifts the synchrotron cooling break up by over a factor of ten, smooths the transition, produces steeper post-break slopes initially, and originates from a narrow frequency-dependent region behind the shock front.

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.
SN2025ulz is a type IIb supernova whose shock-cooling tail mimicked a kilonova, demonstrating a key contaminant for gravitational-wave counterpart searches.
Latest GW neutron star merger rates are consistent with short GRBs being produced by BNS mergers if jets are wide or rates low, with NSBH mergers subdominant.

Moving-mesh simulations of spreading dynamics and local electron cooling in structured gamma-ray burst afterglow jets
Structured GRB jet simulations find that local electron cooling shifts the synchrotron cooling break up by over a factor of ten, smooths the transition, produces steeper post-break slopes initially, and originates from a narrow frequency-dependent region behind the shock front.

Wide Jets or Low Rates: Reconciling Short GRB and Gravitational-Wave Neutron Star Merger Rates
Latest GW neutron star merger rates are consistent with short GRBs being produced by BNS mergers if jets are wide or rates low, with NSBH mergers subdominant.
