High-Energy Spectral Complexity from Thermal Gradients in Black Hole Atmospheres
J. G. Skibo, C. D. Dermer
We show that Compton scattering of soft photons with energies near 100 eV in thermally stratified black-hole accretion plasmas with temperatures in the range 100 keV - 1 MeV can gi…
Method for Organizing the Multiwavelength Data of Radio-Loud Active Galactic Nuclei
Reinhard Schlickeiser, Charles D. Dermer
The broadband emission observed from radio galaxies, BL Lac objects and quasars is thought to be produced by energetic electrons confined in plasma blobs which are ejected from sup…
Stochastic Particle Acceleration near Accreting Black Holes
Charles D. Dermer, James A. Miller, Hui Li
We consider the stochastic acceleration of particles which results from resonant interactions with plasma waves in black hole magnetospheres. We calculate acceleration rates and es…
Cosmological Models of Gamma-Ray Bursts
Charles D. Dermer, Thomas J. Weiler
We review models of cosmological gamma-ray bursts (GRBs). The statistical and -ray transparency issues are summarized. Neutron-star and black-hole merger scenarios are described…
Reverberation mapping of the central regions of active galactic nuclei using high-energy gamma-ray observations
M. Böttcher, C. D. Dermer
We calculate the time- and energy-dependent opacity of high-energy gamma-rays attenuated by pair production interaction with accretion-flare photons that are scattered by gas and d…
