Fermi telescope: 'Violent cosmos' map gets more extreme


www.bbc.co.uk said:

The Fermi space telescope has updated its catalogue of the Universe's most violent neighbourhoods.

Fermi catches gamma rays, the most energetic light, spewing from nature's most extreme physical processes.

The new catalogue, posted on the Arxiv server, lists the sources of the highest-energy gamma rays that Fermi has yet seen: 514 of them.

"Unknown source" just invites speculation.  Isn't it so that matter/antimatter annihilation would produce gamma rays of this sort?
