Daniel Perley is a Reader of Astrophysics at the Astrophysics Research Institute at Liverpool John Moores University. He is an observational astronomer who studies supernovas and other types of cosmic explosion. He received his PhD at the University of California, Berkeley in 2011 and has previously worked at Caltech and at the University of Copenhagen.
For example, if the star is rotating at the time of collapse, some of the infalling material may be focused into jets that escape the star at high velocity. While these jets wouldn't contain much mass, they'd pack a big punch: if they slammed into something, the effects might be quite dramatic in terms of the energy released.
While this doesn't mean a black hole can't have been formed in such an explosion, some have concluded that other models provide a more natural explanation for gamma ray bursts than a black hole forming. For example, a My colleagues and I, however, recently uncovered a new and much better candidate event for creating a black hole.
This is exactly what you would expect if, during the collapse of its core, the star ejected only a small amount of material with the rest of the object collapsing downward into an enormous black hole.
