The article seems to imply that the reason for the unusually long period of gamma bursts being visible is because the remnants of the exploding star is near the centre of that galaxies nucleaus, and hence probably near the supermassive black hole. It goes on to say that the observable event is a stream of this energy towards the sm-bh.
Is this the most logical hypothesis for this event?
What other possibilities could explain such a lengthy burst of gamma radiation being visible?
If it is even speculation that it is a star being ripped apart, then what other possibilites could explain the explosion that lead to the unusually long bursts?
