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.
The Argus Array and DSA are projected to detect 47 and 82 long GRB afterglows per year respectively from Fermi triggers, along with over 100 independent detections annually and some short GRB counterparts.
Detailed photometric, spectroscopic, and modeling study of a low-redshift GRB-SN yielding nickel mass 0.4-0.5 solar masses, ejected mass 4-6 solar masses, and evidence for large-offset explosion in sub-solar metallicity gas.
Simulations of the BSD instrument for POLAR-2 show it can localize faint GRBs like GRB 170817A to about 1.5 degrees accuracy, meeting requirements for supporting GRB polarimetry.
Next-generation CMB experiments are expected to detect thousands of strongly lensed galaxies to z~6 and proto-clusters, plus tens of thousands of local dusty galaxies and radio sources, enabling new studies of galaxy formation.
