Analyzing the Multiwavelength Spectrum and Variability of BL Lacertae During the July 1997 Outburst
Abstract
The multiwavelength spectrum of BL Lacertae during its July 1997 outburst is analyzed in terms of different models for the production of high-energy radiation from blazars. We find that a two-component $\gamma$-ray spectrum, consisting of a synchrotron self-Compton and an external Compton component, is required in order to yield an acceptable fit to the broadband spectrum. Our analysis indicates that in BL Lac, unlike other BL Lac objects, the broad emission line region plays an important role for the high-energy emission.Keywords
