Multiwavelength Analysis of NGC1275/3C84 — •Lena Linhoff — TU Dortmund, Dortmund, Germany

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 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 multi-wavelength analysis results.
