Propagation of strong electromagnetic waves in tenuous plasmas
Emanuele Sobacchi, Masanori Iwamoto, Lorenzo Sironi +1
We study the propagation of electromagnetic waves in tenuous plasmas, where the wave frequency, , is much larger than the plasma frequency, . We show that in pair p…
Filamentation of Fast Radio Bursts in magnetar winds
Emanuele Sobacchi, Yuri Lyubarsky, Andrei Beloborodov +1
Magnetars are the most promising progenitors of Fast Radio Bursts (FRBs). Strong radio waves propagating through the magnetar wind are subject to non-linear effects, including modu…
Synchrotron-Self-Compton radiation from magnetically-dominated turbulent plasmas in relativistic jets
Emanuele Sobacchi, Lorenzo Sironi, Andrei M. Beloborodov
Relativistic jets launched by rotating black holes are powerful emitters of non-thermal radiation. Extraction of the rotational energy via electromagnetic stresses produces magneti…
A fully-kinetic model for orphan gamma-ray flares in blazars
Emanuele Sobacchi, Joonas Nättilä, Lorenzo Sironi
Blazars emit a highly-variable non-thermal spectrum. It is usually assumed that the same non-thermal electrons are responsible for the IR-optical-UV emission (via synchrotron) and…
Self-modulation of Fast Radio Bursts
Emanuele Sobacchi, Yuri Lyubarsky, Andrei M. Beloborodov +1
Fast Radio Bursts (FRBs) are extreme astrophysical phenomena entering the realm of non-linear optics, a field developed in laser physics. A classical non-linear effect is self-modu…
Hard Synchrotron Spectra from Magnetically Dominated Plasma Turbulence
Luca Comisso, Emanuele Sobacchi, Lorenzo Sironi
Synchrotron emission from astrophysical nonthermal sources usually assumes that the emitting particles are isotropic. By means of large-scale two- and three-dimensional particle-in…
