Radiation and Polarization Signatures from Magnetic Reconnection in Relativistic Jets--I. A Systematic Study
Haocheng Zhang, Xiaocan Li, Dimitrios Giannios +3
Blazars are relativistic magnetized plasma outflows from supermassive black holes that point very close to our line of sight. Their emission is nonthermal dominated and highly vari…

Kink Instabilities In Relativistic Jets Can Drive Quasi-Periodic Radiation Signatures
Lingyi Dong, Haocheng Zhang, Dimitrios Giannios
Relativistic jets are highly collimated plasma outflows emerging from accreting black holes. They are launched with a significant amount of magnetic energy, which can be dissipated…

Extreme scattering events from axisymmetric plasma lenses
Lingyi Dong, Maria Petropoulou, Dimitrios Giannios
Frequency-dependent brightness fluctuations of radio sources, the so-called extreme scattering events (ESEs), have been observed over the last three decades. They are caused by Gal…
