Radiative signatures of electron-ion shocks in BL Lac type objects
A. Arbet-Engels, A. Bohdan, F. Rieger +2
Shocks are promising sites of particle acceleration in extragalactic jets. In electron-ion shocks, electrons can be heated up to large Lorentz factors, making them an attractive sc…
Signature of Particle Diffusion on the X-ray Spectra of the blazar Mkn 421
C. Baheeja, S. Sahayanathan, F. M. Rieger +1
The curvature in blazar spectrum has the potential to understand the particle dynamics in jets. We performed a detailed analysis of simultaneous Swift-XRT (0.3-10 keV) and NuSTAR (…
The role of stochastic Fermi-type particle acceleration in the inner jets of Active Galactic Nuclei
Jieshuang Wang, Frank M. Rieger, Yosuke Mizuno
High-resolution radio observations of nearby active galactic nuclei have revealed extended, limb-brightened structures in their inner jets. This ties in with other multi-wavelength…
Optical circular polarization of blazar S4 0954+65 during high linear polarized states
I. Liodakis, E. Shablovinskaya, D. Blinov +17
Optical circular polarization observations can directly test the particle composition in black holes jets. Here we report on the first observations of the BL Lac type object S4 095…
