TL;DR
This paper reviews recent gamma-ray observations of blazars, suggesting that secondary gamma-rays from electromagnetic cascades significantly contribute to their spectra between 1 and 500 GeV.
Contribution
It introduces the idea that electromagnetic cascades may play a dominant role in shaping blazar gamma-ray spectra, based on recent observational evidence.
Findings
Secondary gamma-rays contribute significantly to spectra
Electromagnetic cascades influence observable gamma-ray features
Spectral analysis indicates cascade dominance in 1-500 GeV range
Abstract
We present a very brief overview of some recent gamma-ray observations of selected blazars to reveal an indication for a considerable or even dominant contribution of secondary gamma-rays from electromagnetic cascades to the observable spectra in the 1-500 GeV energy range.
