Multiwavelength Analysis of NGC1275/3C84

The radio galaxy 3C 84 is a well studied source of radio emission and was detected as misaligned blazar NGC 1275 also in the very high-energy regime by gamma-ray detectors like MAGIC and FermiLAT. Unless the innermost structure of 3C 84 can be resolved with radio observations at 43 GHz, the mechanisms producing gamma-ray emission are still not fully understood. A necessary step to understand the production of high-energy photons, is to localize the emission region of gamma-rays in the central region of the source. For this aim, we use photo absorption and calculations of the optical depth within the broad line region to constrain the origin of the gamma-ray emission. In this talk we place our results in the context of theoretical models and other multiwavelength analysis results.
