Intergalactic electromagnetic cascade component of observable blazar emission
T. A. Dzhatdoev, E. V. Khalikov, A. P. Kircheva +1
Secondary γ-rays from intergalactic cascades may contribute to observable spectra of blazars, also modifying observable angular and temporal distributions. In this paper we briefly…
The VHE anomaly in blazar spectra and related phenomena
T. Dzhatdoev, E. Khalikov, A. Kircheva +1
Most of the recent research on extragalactic -ray propagation focused on the study of the absorption process ("absorption-only model"). Starting from…
Testing models of extragalactic -ray propagation using observations of extreme blazars in GeV and TeV energy ranges
T. A. Dzhatdoev, E. V. Khalikov, A. P. Kircheva +1
We briefly review contemporary extragalactic γ-ray propagation models. It is shown that the Extragalactic Magnetic Field (EGMF) strength and structure are poorly known. Strict lowe…
Indications for a cascade component in γ-ray blazar spectra
S. Baklagin, T. Dzhatdoev, E. Khalikov +2
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 gam…
