Although there is strong support for the collapsar engine as the power source of long-duration gamma-ray bursts (GRBs), we still do not definitively know the progenitor of these explosions. Here we review the current set of progenitor scenarios for long-duration GRBs and the observational constraints on these scenarios. Examining these, we find that single-star models cannot be the only progenitor for long-duration GRBs. Several binary progenitors can match the solid observational constraints and also have the potential to match the trends we are currently seeing in the observations. Type Ib/c supernovae are also likely to be produced primarily in binaries; we discuss the relationship between the progenitors of these explosions and those of the long-duration GRBs.

  1. SN 2023rve: A Type II Supernova with No Nebular Oxygen

    astro-ph.HE 2026-06 unverdicted novelty 4.0 of 10

    SN 2023rve exhibits absent [O I] nebular lines with inferred 14-18 solar mass progenitor, 0.27e51 erg explosion energy, and 0.0064 solar mass nickel, possibly indicating partial fallback.

  2. The long-short GRB connection

    astro-ph.HE 2024-12 conditional novelty 4.0 of 10

    Short gamma-ray bursts may be the merged descendants of long gamma-ray bursts formed in binary-driven hypernovae, with rates, redshifts, and host-galaxy offsets all consistent with this evolutionary link.
