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…
Neutrinos from stochastic acceleration in black hole environments
M. Lemoine, F. Rieger
Recent experimental results from the IceCube detector and their phenomenological interpretation suggest that the magnetized turbulent corona of nearby X-ray luminous Seyfert galaxi…
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…
