One of the most challenging quests of current astrophysics is to understand the physical conditions and processes responsible for the production of high-energy particles, and the emission of gamma-rays. Since its launch in 2008, the Fermi-LAT (Large Area Telescope) has revolutionized our knowledge of gamma-ray sky. Blazars, active galactic nuclei in which one of the relativistic jets points close to the observer's line-of-sight, form a major population of the gamma-ray sky and are potential targets for this study. In this talk, the speaker will provide an overview of gamma-ray properties of blazars and the available techniques which could be used to pinpoint the high-energy emission sites. She will briefly highlight open questions and particularly promising avenues for progress.
