The Future of Gamma-Ray Experiments in the MeV-EeV Range
Kristi Engel, Jordan Goodman, Petra Huentemeyer +95
Gamma-rays, the most energetic photons, carry information from the far reaches of extragalactic space with minimal interaction or loss of information. They bring messages about par…
Limits to gauge coupling in the dark sector set by the non-observation of instanton-induced decay of Super-Heavy Dark Matter in the Pierre Auger Observatory data
