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.
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.
No kilonova detected from sub-solar GW candidate S251112cm, but coincident IIb supernova SN 2025adtq yields suggestive evidence for the superkilonova channel, though inconclusive after accounting for chance coincidence.
Self-lensing signals occur with probabilities of roughly 10^{-3} in WD+NS systems and 10^{-2} in WD+BH systems; TESS could detect at least one if 8% of white dwarfs have NS companions and 3% have BH companions, while Roman cannot.
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.
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.
Host galaxy analysis rules out a globular cluster origin for the GRB 230307A kilonova and shows a disk-formed BNS merger with natal kicks can reach the observed offset in only 0.1% of population-synthesis realizations.
