Abstract

We think that gamma-ray bursts have two types of progenitors, each of them producing flashes with different durations, long or short. In December 2021, the most bizarre burst ever not only broke our progenitor paradigm, but also showed a late-time excess of gamma-rays never observed before. Both these mysteries have a common protagonist: the coincident detection of a kilonova.
