Recently about the Extragalactic Jets 2007 Alaska Conference Lawrence Rudnick wrote:
"R. Protheroe deserves kudos for an extremely innovative proposal to use fossil AGN as the source of ultra-high-energy cosmic rays. The basic idea is that fossil jets self-organize into a stable reverse-field pinch (RFP) configuration. The slow decay of this field through reconnection induces electric fields of order 10−5 V/m, which can then accelerate seed cosmic rays to high energies. Whether or not this RFP mechanism will ultimately work, it may provide the stimulus for more creative thinking about the sources of the highest energy cosmic rays."
When workers in different fields start to quote each other, you know that something big may be coming.
