Nonlinear feedback of the electrostatic instability on the blazar-induced pair beam and GeV cascade
Mahmoud Alawashra, Martin Pohl
Relativistic pair beams produced in the cosmic voids by TeV gamma rays from blazars are expected to produce a detectable GeV-scale cascade that is missing in the observations. The…
Interpolation of Instrument Response Functions for the Cherenkov Telescope Array in the Context of pyirf
Rune Michael Dominik, Maximilian Linhoff, Julian Sitarek
The Cherenkov Telescope Array (CTA) will be the next generation ground-based very-high-energy gamma-ray observatory, constituted by tens of Imaging Atmospheric Cherenkov Telescopes…
Variability studies of active galactic nuclei from the long-term monitoring program with the Cherenkov Telescope Array
Guillaume Grolleron, Josefa Becerra González, Jonathan Biteau +13
Blazars are active galactic nuclei (AGN) with a relativistic jet oriented toward the observer. This jet is composed of accelerated particles which can display emission over the ent…
Evolution of Relativistic Pair Beams: Implications for Laboratory and TeV Astrophysics
Marvin Beck, Oindrila Ghosh, Florian Grüner +5
Missing cascades from TeV blazar beams indicate that collective plasma effects may play a significant role in their energy loss. It is possible to mimic the evolution of such highl…
Electron-Ion Temperature Ratio in Astrophysical Shocks
John C. Raymond, Parviz Ghavamian, Artem Bohdan +9
Collisionless shock waves in supernova remnants and the solar wind heat electrons less effectively than they heat ions, as is predicted by kinetic simulations. However, the values…
Pre-acceleration in the Electron Foreshock II: Oblique Whistler Waves
Paul J. Morris, Artem Bohdan, Martin S. Weidl +3
Thermal electrons have gyroradii many orders of magnitude smaller than the finite width of a shock, thus need to be pre-accelerated before they can cross it and be accelerated by d…
