We present a phenomenological model to explain the light curves of gamma-ray bursts. In the model a black hole is orbited by a precessing accretion disc which is fed by a neutron star. Gamma-rays are produced in a highly collimated beam via the Blandford-Znajek mechanism. The gamma-ray beam sweeps through space due to the precession of the slaved accretion disc. The light curve expected from such a precessing luminosity cone can explain the complex temporal behavior of observed bright gamma-ray bursts.

  1. The Very Late Time Afterglow of GW170817 Favors a Wobbling Jet

    astro-ph.HE 2026-05 unverdicted novelty 6.0

    A ring-shaped wobbling jet explains the shallow late-time afterglow decay of GW170817 better than a collimated jet at 4.8 sigma significance, implying a ~27 degree wobble angle.
