Physics - Galaxy's Gamma Glow Illuminates Cosmic-Ray Origins

Interstellar magnetic fields perturb the trajectories of cosmic rays, making it difficult to identify their sources. A new survey of gamma radiation produced when cosmic rays interact with the interstellar medium should help in this identification.

High-energy particle accelerators within our galaxy discovered -- Science & Technology -- Sott.net

Fri, 02 Apr 2021 17:48 UTC Move over, CERN. Unknown sources in the Milky Way dubbed PeVatrons accelerate protons to energies of a few peta-electronvolts - dozens of times higher than the yield of the Large Hadron Collider. Now, new data from a high-altitude experiment in Tibet confirm that such very-high-energy cosmic rays are indeed produced in our own galaxy. © APS; Background (atomic hydrogen distribution): HEASARC / LAMBDA / NASA / GFSC Ultra high-energy diffuse gamma rays (yellow points) are distributed along the Milky Way Galaxy. The gray shaded area indicates the area outside the detectors field of view. The results paint a much fuller picture of the PeVatron population in the Milky Way, says Pat Harding (Los Alamos National Laboratory), who was not involved in the study.
