AGNs - source of high-energy cosmic rays

According to New Scientist, Nov 17 2007:

The Auger researchers analysed all 27 of the most energetic cosmic rays... and found that almost all seemed to come from AGNs less than 250 million light years away...

However... astronomers can't yet rule out the possibility that some high-energy cosmic rays come from gamma-ray bursts

AGNs are Active Galactic Nuclei, of which the nearest is our own Galactic Center - which so far does not appear to spit out cosmic rays, but you'd be foolish to think that this means it won't.
