Graduate Student Seminar with Mehrnoosh Rahbardar Mojaver on Pick the PIC Peak

Active Galactic Nuclei (AGNs) are one of the most luminous objects in the universe and their emission has been the subject of many research projects since their discovery. Such emission from Blazars, which are the AGNs that emit their jet in the line of sight of the observer, shows several interesting features. Their spectra include two humps that indicate the large part of the synchrotron cooling in its emission process. The other characteristic that could lead to a better understanding of the Blazars jet’s structure and the acceleration process is the polarization of the radiation. One of the most effective ways of producing such an environment of relativistic non-thermal radiating accelerated particles is kink instability presence in the jet plasma. One of the most efficient ways to simulate particles acceleration in presence of electromagnetic forces and synchrotron cooling is Particle in Cell (PIC) simulation which involves first principle kinetic simulation. Here I try to explain: How PIC works, Why MHD is not a good simulation for such an environment, and What other mechanisms there are for having jets.
