Abstract

Za blazar Mrk421 je 2013. godine zabilježena iznimno visoka aktivnost u gama i X-području elektromagnetskog spektra. Cilj ovog rada je napraviti fizikalni model koji uključuje dvije komponente, tj. dvije sfere magnetizirane visokoenergetske plazme. Pod pretpostavkom da svo opaženo zračenje dolazi od sinkrotronskog i inverznog Comptonovog zračenja elektrona, ostvareno je programsko rješenje koje omogućuje izračun očekivane emisije u svim dijelovima spektra iz tih komponenti. Zatim je odabrana, i u programskom rješenju implementirana, odgovarajuća metoda za prilagodbu teorijskog modela na podatke te su pronađeni najvjerojatniji parametri modela. Pri modeliranju je uzeta u obzir i vremensku evolucija komponenti.

Abstract (english)

In 2013, extremely high activity in the gamma and X-region of the electromagnetic spectrum was recorded for blazar Mrk421. The aim of this paper is to make a physical model that includes two components, i.e. two spheres of magnetized high-energy plasma. Assuming that all the observed radiation comes from the synchrotron and inverse Compton radiation of the electron, a software solution was realized that allows the calculation of the expected emission in all parts of the spectrum from these components. Then, the appropriate method for adapting the theoretical model to the data was selected and implemented in the software solution, and the most probable parameters of the model were found. The temporal evolution of the components was also taken into account while modeling.
