Spectral energy distributions and high-energy emission of BL Lac type objects
Abstract Based on identifications from the Véron and Quasars.org catalogues, we determine the optical-to-X-ray spectral indices for a sample of 201 BL Lac type objects (BLLs) and search for trends in the distribution of these indices of the sources detected in high-energy bands. We find that EGRET-d...
