The Puzzling Long GRB 191019A: Evidence for Kilonova Light

GRB 191019A was a long gamma-ray burst (GRB) lasting ~65 s and, as such, originally thought to be linked to a core-collapse supernova. However, even though follow-up observations identified the optical counterpart close to the bright nucleus of a nearby ancient galaxy ( z = 0.248), no associated sup...
