SPECTRAL RELATION BETWEEN X-RAYS AND GAMMA RAYS FOR BLAZAR HIGH-ENERGY EMISSION

摘要

We collect 10 active galactic nuclei with both X-ray and gamma-ray spectral data. A correlation is found between X-ray and gamma-ray spectral indices. Possible constraints on existing models for gamma-ray emission are discussed. A new model involving inverse-Compton scattering of beamed relativistic electrons in the full cross section is outlined to account for this spectral relation.
