Synchrotron-Regulated Relativistic Magnetohydrodynamic Turbulence: Emission, Polarization, and Faraday Rotation
Xiaochen Sun, Luca Comisso, Luca Comisso Lorenzo Sironi +3
Relativistic magnetized plasmas in many high-energy astrophysical systems are both turbulent and strongly radiative, yet their nonlinear dynamics and radiative outcomes remain poor…
Reconnection-Driven Turbulent Fluctuations in the Magnetically Dominated Collisionless Regime
Yue Hu, Luca Comisso, Lorenzo Sironi +1
Magnetic reconnection is a fundamental plasma process that converts magnetic energy into bulk flow energy, thermal energy, and nonthermal particle acceleration. Despite its importa…
Diffuse neutrino flux from relativistic reconnection in AGN coronae
D. Karavola, M. Petropoulou, D. F. G. Fiorillo +3
IceCube observations point to Active Galactic Nuclei (AGN) as promising contributors to the observed astrophysical neutrino flux. Close to the central black hole, protons can be ac…
Neutrinos and gamma rays from Seyfert galaxies constrain the properties of coronal turbulence
Federico Testagrossa, Damiano F. G. Fiorillo, Luca Comisso +3
The TeV neutrino signal observed by IceCube from the active galactic nucleus (AGN) NGC 1068 can probe its innermost coronal regions. If these neutrinos originate from hadrons accel…
The role of Bethe-Heitler pair production in reconnection-driven flares in M87*
Maria Petropoulou, Despina Karavola, Lorenzo Sironi
Rapid TeV flares have been observed from the core of the active galaxy M87. These have been attributed to inverse Compton scattering of disk photons by electrons and positrons acce…
Superluminal Wave Activation at Relativistic Magnetized Shocks
Jens F. Mahlmann, Logan Eskildsen, Arno Vanthieghem +2
Fast radio bursts (FRBs) are extremely energetic radio transients, some are generated in magnetar magnetospheres and winds. Despite a growing number of observations, their emission…
