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.
A second coherent radio burst spanning 704-4032 MHz with spectral index -2.18, 54% linear and 22% circular polarization, and an orthogonal polarization angle jump was detected from 2XMM J104608.7-594306, showing rare radio activity in sources thought to be radio-quiet.
Machine learning on precursor emission in 366 GRBs yields a simple prompt-only index EPI that separates merger-driven from collapsar-driven bursts at a threshold of 6.2.
Numerical modeling shows GRB 230307A's late-time prompt emission break is best reproduced by a jet with uniform core of 0.0147 rad and power-law wings, unlike simpler spherical or top-hat models.
Forecasts show that ~66 optical GRBs can achieve σ_w ≈ 0.47 in wCDM using Dainotti relations, matching Planck precision and enabling independent high-redshift tests of dark energy.

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.
