Cosmic connections: from cosmic rays to gamma rays, to cosmic backgrounds and magnetic fields
Alexander Kusenko
Combined data from gamma-ray telescopes and cosmic-ray detectors have produced some new surprising insights regarding intergalactic and galactic magnetic fields, as well as extraga…
TeV gamma rays from blazars beyond z=1?
Felix Aharonian, Warren Essey, Alexander Kusenko +1
At TeV energies, the gamma-ray horizon of the universe is limited to redshifts z<<1, and, therefore, any observation of TeV radiation from a source located beyond z=1 would call fo…
Time structure of gamma-ray signals generated in line-of-sight interactions of cosmic rays from distant blazars
Anton Prosekin, Warren Essey, Alexander Kusenko +1
Blazars are expected to produce both gamma rays and cosmic rays. Therefore, observed high-energy gamma rays from distant blazars may contain a significant contribution from seconda…
