Can the gamma ray bursts connected to a new supernova prevent the black hole from forming?
Quoting the abstract of the linked reference "...has become clear that probably all long GRBs are associated with type-Ic supernovae resulting from massive stars that suffered substantial mass loss...".
If enough mass is converted into radiated energy then the condition for BH formation can vanish?
More recently, a consensus had grown up that GRB’s (as they are called) are associated with intense beams of particles created by newly-born supernovae. That’s a model that seems to fit most of the data, anyway, and it also makes a pretty good prediction for the production of associated neutrinos. But a new paper by the marvelous IceCube experiment has thrown a spanner into the works: they should have been able to see those neutrinos, and they don’t.
