Hey guys having a bit of problem with my year 1 essay.
Would really appreciate any help :)

What are the main sources of gamma ray bursts both short and long duration?

I know some are from supernovae but where do others come from?

There are several threads at PF regarding Gamma Ray Bursts (GRBs). The threads contain links to papers and sites from government (e.g. NASA, ESA), research and educational institutions.
