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.
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.
Binary evolution simulations identify short (20-500 days) and long (2000-4000 days) orbital period ranges where massive star-black hole systems retain enough angular momentum for GRB jet production with negligible mass loss.
