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…

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…

Intermittency in Collisionless Large-Amplitude Turbulence

Ryan Golant, Luca Comisso, Philipp Kempski +1

Large-amplitude turbulence -- characterized by a fluctuating magnetic field component, , that is stronger than the mean component, -- is generically intermittent, populat…

Diffuse neutrino flux from coronal magnetospheric current sheets of accreting black holes

Despina Karavola, Maria Petropoulou, Damiano F. G. Fiorillo +2

Non-jetted AGN exhibit hard X-ray emission with a power law spectrum above 2 keV, which is thought to be produced through Comptonization of soft photons by electrons and posi…

Filamentation of the electromagnetic precursor in relativistic quasi-perpendicular electron-positron shocks

Emanuele Sobacchi, Yuri Lyubarsky, Lorenzo Sironi +1

We present a scenario that could explain non-thermal particle acceleration in relativistic quasi-perpendicular electron-positron shocks, such as the termination shock of pulsar win…

On the universality of the split monopole black hole magnetosphere

S. Selvi, O. Porth, B. Ripperda +1

Black holes can acquire magnetic flux from their magnetized progenitor or via prolonged accretion. We study the evolution of black hole magnetospheres by means of axisymmetric gene…
