A tool to understand emission mechanisms of blazars through their high-energy gamma-ray emission

The blazar SED is characterized by two energy components. Evidence suggests that the low-energy component is generated by the synchrotron mechanism, but for the high-energy component, the mechanism is still uncertain. Two main models have been proposed to explain this emission. According to the leptonic model, a correlation between the emission of both SED components would be expected, while the hadronic model would explain the highest gamma ray and neutrino emission. The particle acceleration processes inside the relativistic jets of AGNs remain another open question. This article presents a summary of some studies that leverage high-energy gamma-ray emissions to enhance our understanding of the particle acceleration and emission mechanisms of blazars.
