Scope
Energization of particles is the cornerstone for the most of bright astrophysical phenomena in the Solar system and beyond. Solar flares, pulsars, jets launched by accreting black hole in active galaxies and microquasars and accretion discs around compact objects shine thanks to the dramatic energy release with associated particle acceleration. Which processes lead to energy output, how particles lose their energy to radiation and what are the observational signatures? These are the open questions to be answered by the modern numerical laboratories.
Particle acceleration in these sources is successfully studied in the kinetic approach, while structure and evolution of the systems can only be probed with fluid approximation. Radiation so far has been treated predominantly using phenomenological description. With the growth of computing capabilities, hybrid approaches start to emerge. Coupling of radiation processes with the PiC simulations as well as embedding the PiC methods into an MHD framework becomes feasible, and the next-generation codes are being developed to perform ab-initio calculation on the global scale, setting new horizons in the studies of high-energy astrophysical phenomena.
The workshop aims to discuss the state-of-the-art approaches, challenges for the next-generation hybrid MHD-PiC and radiation-PiC methods and outline the problems to be answered by the new exascale simulations of Nature in silico. It will bring together experts in high-performance computing, numerical methods, plasma physics, and radiative processes.
