Turbulent Magnetogenesis and Large-scale Magnetic Dynamo Amplification in Ion--electron Plasmas
Fabio Bacchini, Francesco Pucci, Sergio Servidio +2
Using fully kinetic simulations that capture unprecedentedly large (from electron to ion) scales, we study magnetogenesis driven by continuous large-scale forcing until nonlinear d…
Numerical simulations of waves and turbulence in coronal loops: observables and spectra
Fabio Feraco, Francesco Pucci, Claudio Meringolo +11
We investigate numerically the time evolution of velocity and magnetic field fluctuations in a coronal loop, focusing on the dynamics due to both phase mixing and turbulent cascade…
Assessing VBz variations during CME propagation: a preparatory study for the HENON mission using EUHFORIA
G. Prete, A. Niemela, S. Poedts +21
Coronal mass ejections (CMEs) are among the main drivers of space weather hazards. In this context, HENON is a new space mission designed to carry out observations in the solar win…
The Role of Inhomogeneities in the Turbulent Accretion of Black Holes
Giuseppe Ficarra, Michele Arcuri, Rita Megale +1
Observations of supermassive black holes by the Event Horizon Telescope reveal significant inhomogeneities, most likely related to density and magnetic field perturbations. To mode…
Numerical investigation of kinetic instabilities in BGK equilibria under collisional effects
Sofia Zanelli, Gabriele Celebre, Sergio Servidio +1
An unstable one-dimensional Bernstein-Greene-Kruskal (BGK) mode has been studied through high-precision numerical simulations. The initial turbulent, periodic equilibrium state is…
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…
