What research challenges are going on for grbs and supernovae?

In a cosmic first, researchers have observed the most powerful and luminous yet known energy release — a trillion times more energetic than visible light — in the brightest type of electromagnetic events known to occur in the universe called gamma-ray bursts (GRBs).
The study, published in the journal Nature, noted that the very high energy cosmic emission had been predicted earlier in theoretical studies, and thought to originate from collapsing stars or from the merging of two dying stars, but never directly observed until now.
The researchers, including those from George Washington University in the US, detected a burst on 14 January labeled GRB 190114C, which led to a collaborative effort to observe the radiation coming from the source using more than 20 observatories and instruments around the world.
