PIC simulations of nonrelativistic high-Mach-number oblique shocks propagating in a turbulent medium
Karol Fulat, Eloise Moore, Mahmoud Alawashra +4
Collisionless shocks are common in astrophysical systems and stand as sites of particle acceleration. While particles at perpendicular shocks may not return to the upstream region,…
Hillas meets Eddington: The case for blazars as ultra-high-energy neutrino sources
Xavier Rodrigues, Frank Rieger, Artem Bohdan +1
Blazars are promising high-energy neutrino source candidates. However, leptohadronic models face challenges in describing neutrino emission within a viable energy budget, and their…
Radiative signatures of electron-ion shocks in BL Lac type objects
A. Arbet-Engels, A. Bohdan, F. Rieger +2
Shocks are promising sites of particle acceleration in extragalactic jets. In electron-ion shocks, electrons can be heated up to large Lorentz factors, making them an attractive sc…
Neural Networks for the Analysis of Traced Particles in Kinetic Plasma Simulations
Gabriel Torralba Paz, Artem Bohdan, Jacek Niemiec
Cosmic-ray acceleration processes in astrophysical plasmas are often investigated with fully-kinetic or hybrid kinetic numerical simulations, which enable us to describe a detailed…
