Study On The Acceleration And Radiation Theory Of High Energy Electrons

We summery the general nature of AGNs and blazers, detailing radiation process and inverse Compton scattering process, and derive the formula to calculate the inverse Compton radiation flux and synchrotron radiation flux under the uniform SSC model,and analyzes the approximate analytic solution of pitch-angle-averaged synchrotron spectral power of a single electron. Then, we study the Monte Carlo simulation for inverse Compton scattering in homogeneous isotropic relativistic plasma media. At last, We review the theoretical acceleration high-energy particle and the formation mechanism for common electron spectrum.We have modeled the average(2009.3.15-2009.5.1) broadband spectrum of Mrk501(from radio to TeV) in the framework of the standard one-zone SSC model in which a broken power law electronic enengy spectrum was assumed, obtaining a satisfactory fit to the experimental data. It imply that a non-relativistic shock propagate in the dominant radiation zone of Mrk501 jet,and there are approximately equal numbers of relativistic electrons and protons in shocked plasma, particles undergoing diffusive(first-order Fermi) shock acceleration at the shock front, and cooling radiatively in the downstream region of the shock. Meanwhile some particles escape from the downstream region, and the electronic enengy spectrum can be approximated by a broken power law in this situation. We also find that the ultrarelativistic electrons and mildly relativistic protons within the blazar zone, if comparable in number,are in approximate energy equipartition, with their energy dominating the jet magnetic field energy by about two orders of magnitude, and the total jet power constitutes only a small fraction(0.001) of the Eddington luminosity.
