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,…
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…
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…
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…
Electrostatic Waves and Electron Holes in Simulations of Low-Mach Quasi-Perpendicular Shocks
Artem Bohdan, Aaron Tran, Lorenzo Sironi +1
Collisionless low Mach number shocks are abundant in astrophysical and space plasma environments, exhibiting complex wave activity and wave-particle interactions. In this paper, we…
Diffusive shock acceleration in relativistic, oblique shocks
Allard Jan van Marle, Artem Bohdan, Anabella Araudo +2
Cosmic rays are charged particles that are accelerated to relativistic speeds by astrophysical shocks. Numerical models have been successful in confirming the acceleration process…
