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…
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…
Prediction and Anomaly Detection of accelerated particles in PIC simulations using neural networks
Gabriel Torralba Paz, Artem Bohdan, Jacek Niemiec
Acceleration processes that occur in astrophysical plasmas produce cosmic rays that are observed on Earth. To study particle acceleration, fully-kinetic particle-in-cell (PIC) simu…
Using PIC and PIC-MHD to investigate cosmic ray acceleration in mildly relativistic shocks
Artem Bohdan, Anabella Araudo, Allard Jan van Marle +2
Astrophysical shocks create cosmic rays by accelerating charged particles to relativistic speeds. However, the relative contribution of various types of shocks to the cosmic ray sp…
