Particle acceleration II
- Łukasz Stawarz (Astronomical Observatory, Jagiellonian University)
Relativistic jets of blazars and magnetized coronae of highly accreting black holes routinely display non-thermal emission signatures, including fast and bright flares of high-energy emission. Yet, the “engine” responsible for accelerating the emitting particles to ultra-relativistic energies is still unknown. With fully-kinetic particle-in-cell (PIC) simulations, we will argue that...
Relativistic jets are produced by certain accreting black holes where accumulation of magnetic fields leads to relativistic magnetizations. Magnetic reconnection is one of the most promising mechanisms of energy dissipation and particle acceleration that may operate in the relativistic jets. Magnetic reconnection may be triggered instabilities, in particular the current and pressure driven...
Gamma-Ray Bursts (GRBs) are long-standing cosmic-ray source candidates. It is however unclear how large the fraction of energy transferred to non-thermal protons (often dubbed baryonic loading) can be in order to be still compatible with observed photon spectra. Using the internal shock model for the dynamic evolution of the outflow, we perform self-consistent lepto-hadronic radiation models...
