Beyond Fermi-II: Intermittent Particle Acceleration by Relativistic Turbulence in Astrophysical Plasmas
Anton Dmytriiev, Frans van der Merwe, Markus Böttcher
Stochastic particle acceleration in turbulent plasmas plays a key role in shaping high-energy emission from relativistic outflows, such as those in Active Galactic Nuclei (AGN) and…
Modeling Particle Acceleration and MWL Emission of a PeVatron Microquasar V4641 Sgr
Anton Dmytriiev, Frans van der Merwe, Markus Böttcher
The Large High Altitude Air Shower Observatory (LHAASO) has recently reported five Galactic microquasars as Ultra-High-Energy (UHE) -ray emitters (> 100 TeV). Among these sourc…
Compton-induced -ray Cascade Emissions in Radio Galaxy NGC 1275
Mfuphi Ntshatsha, Markus Böttcher, Soebur Razzaque
Among active galactic nuclei (AGNi), blazars are the brightest emitters of high-energy (HE, MeV) to very-high-energy (VHE, GeV) -rays from their jets.…
The Detection of Teraelectronvolt Radiation from a Flat Spectrum Radio Quasar
Vaidehi S. Paliya, Markus Bottcher, Kiran Wani +5
The very high-energy (VHE; 100 GeV) radiation carries the signatures of the matter-energy interaction in some of the most extreme astrophysical environments. Considering broad e…
Determining the origin of the X-ray emission in blazars through multiwavelength polarization
Ioannis Liodakis, Haocheng Zhang, Stella Boula +48
The origin of the high-energy emission in astrophysical jets from black holes is a highly debated issue. This is particularly true for jets from supermassive black holes that are a…
Searching for Internal Absorption Signatures in High-Redshift Blazars
Anton Dmytriiev, Atreya Acharyya, Markus Böttcher
The gamma-ray emission from Flat Spectrum Radio Quasars (FSRQs), a sub-class of blazars, is believed to be generated through interactions of high-energy leptons and/or hadrons in t…
