Gamma-Ray Bursts: To be Short or Long is not the Question

Abstract

The association of a short gamma-ray burst with a core-collapse supernova seems to challenge current scenarios for the origin of these extreme events. But how much can we rely on observed duration for pinpointing their progenitors?
