I work under a supervision of Prof. Marek Sikora on relativistic jets in active galactic nuclei. Our study focuses on their geometrical structure, energy dissipation mechanisms and non-thermal radiative processes.
Modeling of nonthermal leptonic processes in the context of blazars, including synchrotron radiation with polarization and self-absorption, Inverse Compton scattering with full cross section, evolution of electron distribution, pair production absorption, special-relativistic effects.
Analysis of data from Fermi Large Area Telescope.
