Gamma Ray Bursts as Possible High Energy Sources
Charles D. Dermer
Gamma-ray bursts are known to be sources of high-energy gamma rays, and are likely to be sources of high-energy cosmic rays and neutrinos. Following a short review of observations…
Gamma Rays from Compton Scattering in the Jets of Microquasars: Application to LS 5039
Charles D. Dermer, Markus Boettcher
Recent HESS observations show that microquasars in high-mass systems are sources of VHE gamma-rays. A leptonic jet model for microquasar gamma-ray emission is developed. Using the…
A Class of Exact Solution to the Blandford-Znajek Process
Govind Menon, Charles D. Dermer
We analyze the constraint equation giving allowed solutions describing fields and currents in a force-free magnetosphere around a rotating black hole. Utilizing the divergence prop…
High Energy Cosmic Rays from Local GRBs
A. Atoyan, C. D. Dermer
We have developed a model that explains cosmic rays with energies E between \~0.3 PeV and the energy of the second knee at E_2 ~ 3*10^{17} eV as originating from a recent Galactic…
High-Energy Cosmic Rays and Neutrinos from Gamma-Ray Bursts
C. Dermer
A complete model for the origin of high-energy >~10^{14} eV) cosmic rays from gamma-ray bursts (GRBs) and implications of this hypothesis are described. Detection of high-energy ne…
Cosmic Rays from Gamma Ray Bursts in the Galaxy
Charles D. Dermer, Jeremy M. Holmes
The rate of terrestrial irradiation events by galactic gamma-ray bursts (GRBs) is estimated using recent standard-energy results. We assume that GRBs accelerate high-energy cosmic…
