Where are Cosmic Rays Coming From?

Recently the Pierre Auger Observatory (PAO) reported twenty seven cosmic rays of the highest energy coming from several sources. Two of them came from the direction of Centaurus, maybe from the Cen A Active Galactic Nucleus (AGN).

A group of two Japanese scientists also recently reported a hole in our Galaxy in the direction of Centaurus, as I reported here.

This distortion, as they call it, may explain why there are not that many cosmic rays of these high energies, received at the PAO, coming from Virgo, where there are AGNs almost at the same distance from us as Cen A, as recently observed by Gorbunov et al., as reported here.
