Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Thanks for the update: if there is an AGN in the right direction within a distance of the order of 160 Mlyr then there's no evidence of violations of the GZK cutoff.

Which is rather a pity, because GZK violation was one of very few experimental results not explainable by the standard model of particle physics and the standard cosmological model (another one being the rotation curves of galaxies).
