Plasma turbulence driven by wave-hole interaction
Gabriele Celebre, Mario Imbrogno, Sergio Servidio +1
Wave-obstacle diffraction is, par excellence, an example of transition to nonlinearity, generating turbulence and complexity in fluids. We present an idealized kinetic plasma regim…
Particle-acceleration mechanisms in multispecies relativistic plasmas
Claudio Meringolo, Mario Imbrogno, Alejandro Cruz-Osorio +2
While collisionless plasmas are ubiquitously present near astrophysical compact objects, the impact that their composition has on the high-energy emission is presently unknown. We…
Turbulence and Magnetic Reconnection in Relativistic Multispecies Plasmas
Mario Imbrogno, Claudio Meringolo, Alejandro Cruz-Osorio +3
Simulations of relativistic plasmas traditionally focus on the dynamics of two-species mixtures of charged particles under the influence of external magnetic fields and those gener…
Extreme Gravitational Interactions in the Problem of Three Black Holes in General Relativity
Mario Imbrogno, Claudio Meringolo, Sergio Servidio
We study the three-body problem going from Newtonian mechanics to general relativity. In the classical case, we model the interactions in a typical chaotic configuration, identifyi…
Long-living Equilibria in Kinetic Astrophysical Plasma Turbulence
Mario Imbrogno, Claudio Meringolo, Sergio Servidio +3
Turbulence in classical fluids is characterized by persistent structures that emerge from the chaotic landscape. We investigate the analogous process in fully kinetic plasma turbul…
Measuring the properties of homogeneous turbulence in curved spacetimes
Rita Megale, Alejandro Cruz-Osorio, Giuseppe Ficarra +5
Turbulence in curved spacetimes in general, and in the vicinity of black holes (BHs) in particular, represents a poorly understood phenomenon that is often analysed employing techn…
