Gamma Rays from the Tycho Supernova Remnant: Leptonic or Hadronic?
Armen Atoyan, Charles Dermer
Recent Fermi and VERITAS observations of the prototypical Type Ia supernova remnant (SNR) Tycho have discovered gamma-rays with energies E in the range from ~0.4 GeV to 10 TeV. Cru…
Observational Consequences of GRBs as Sources of Ultra High Energy Cosmic Rays
Soebur Razzaque, Charles D. Dermer, Justin D. Finke +1
Gamma-ray bursts (GRBs) have long been considered as candidates of ultrahigh-energy cosmic rays (UHECRs). We investigate the signatures of CR proton acceleration in the GRBs by con…
Section on Extragalactic Science Topics of the White Paper on the Status and Future of Ground-Based TeV Gamma-Ray Astronomy
H. Krawczynski, A. M. Atoyan, M. Beilicke +32
This is a report on the findings of the extragalactic science working group for the white paper on the status and future of TeV gamma-ray astronomy. The white paper was commissione…
Ultra High Energy Cosmic Rays from Black Hole Jets of Radio Galaxies
C. D. Dermer, S. Razzaque, J. D. Finke +1
The Auger Collaboration reports that the arrival directions of >60 EeV ultra-high energy cosmic rays (UHECRs) cluster along the supergalactic plane and correlate with active galact…
Gamma Rays from Ultra-High Energy Cosmic Rays in Cygnus A
Armen Atoyan, Charles D. Dermer
Ultra-high energy cosmic rays (UHECRs) accelerated in the jets of active galactic nuclei can accumulate in high magnetic field, ~100 kpc-scale regions surrounding powerful radio ga…
Ultra-high energy cosmic rays, cascade gamma-rays, and high-energy neutrinos from gamma-ray bursts
Charles D. Dermer, Armen Atoyan
Gamma-ray bursts (GRBs) are sources of energetic, highly variable fluxes of gamma rays, which demonstrates that they are powerful particle accelerators. Besides relativistic electr…
