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.
GRB 210704A at z=2.34 shows a luminous fast blue transient excess peaking at ~7 days, modeled as refreshed shock emission and linked to LFBOTs alongside a high-Lorentz-factor jet.
SPH simulations of repeated partial disruptions in 16 WD-BH/NS systems predict three categories of periodically modulated X-ray/GRB transients whose durations and peak rates depend on mass ratio and compactness.
First blind optical identification of a z=0.153 sub-luminous GRB afterglow with Ic-BL SN, yielding a volumetric rate consistent with on-axis high-luminosity long GRBs.
A dynamical model of magnetar-driven jet and PWN emission predicts a sequence of thermal, X-ray plateau, and late synchrotron/inverse-Compton radiation that accounts for key features in merger GRBs.
GRB intrinsic duration distributions show a redshift-dependent plateau only at z>2 and for soft bursts, indicating collapsar dominance at high redshift and non-collapsar contributions at low redshift, with progenitor radius constrained to a few tenths of a solar radius.
Kilonova-like emissions after long GRBs GRB211211A and GRB230307A are consistent with collapsar nucleosynthesis using a single weak r-process component without lanthanide-rich material.
Late-time JWST/NIRCam data on GRB 250702B show a high-mass dusty host and possible ~3-sigma transient detections in two bands suggesting light-curve flattening.
Short and long-short GRB rates of 195-666 Gpc^{-3} yr^{-1} exceed the 66-347 Gpc^{-3} yr^{-1} EM-bright NS merger rate from GW observations, challenging a pure NS merger origin.
Lower BNS merger rates from GWTC-4 data produce tensions of factors 3.6-18 with SGRB rates, 0.9-4.1 with r-process rates, and 2.3-5.1 with Galactic DNS 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.
No coincident GW signals found with long GRBs in O3 run; luminosity distance limits set assuming binary merger powering.
The paper proposes a high-redshift (z>2) origin for GRB 061201 by combining afterglow constraints with deep JWST near-infrared imaging of a faint candidate host.
