EP260321a/SN2026gzf is the first Type Ic-BL supernova with a likely X-ray shock breakout, and such bright breakouts may be rare.
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.
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.
GRB 061201 originates from a host at z~1.2 rather than the previously claimed z=0.111, supported by photometric redshift, afterglow AIC modeling, energy relation consistency, and reduced merger rate implications.
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.
A search of repeating FRBs identifies RM flare candidates in FRB 20121102A, FRB 20201124A, and FRB 20180916B, suggesting such events may be common and tied to dynamic magneto-ionic environments.
Non-detection of kilonova from S250206dm excludes AT 2017gfo-like events and disfavors NS-BH mergers with mass ratio Q >= 3.2, reaching GW-comparable precision on the mass gap candidate.
Optical imaging and BAGPIPES SED fitting of eight FXTs yields candidate hosts consistent with WD-IMBH TDEs or BNS mergers for most events, with one reclassified as a Galactic flare and evidence for diverse origins.
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.
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.
