Deflection of Cosmic Rays

Here I report on a calculation by a South American group of physicists. They are:
Gustavo A. Medina Tanco, Elisabete M. de Gouveia Dal Pino, and Jorge E. Horvath.

Deflection of ultra high energy cosmic rays by the galactic field:from the sources to the detector.

Similarly to Takami and Sato, these authors study the UHECR deflection through the Milky Way magnetic field.

They find that a constant magnetic field in the direction of the galactic axis of rotation, this so called "wind" magnetic field, is important for deflection calculations.

"The Galactic Magnetic Field acts as a kind of giant spectral analyzer and the forbidden and allowed regions resemble the situation the dipolar magnetic field of the Earth creates on the low energy cosmic rays."

They also expect when they wrote this paper in 1995, that the PAO will be valuable in determining our galaxy's magnetic field.

In a recent article Charles D. Dermer (see note above) wrote:

"These results establish without doubt that UHECRs originate from astrophysical sources. With this information, and based on past theoretical work, I argue that GRBs and radio-loud AGNs, which are classified as blazars when viewed on-axis, are the most probable sources of UHECRs, as can be demonstrated by hadronic γ -ray signatures. The most convincing evidence would be direct detection of PeV neutrinos from UHECR sources with IceCube or KM3NET. Detection of GZK EeV neutrinos from photopion interactions of UHECRs as they propagate through EBL with an Askaryan telescope like ANITA will also importantly test astrophysical models."
