The near-Earth space is a unique laboratory to explore turbulence and energy dissipation
processes in magnetized plasmas thanks to the availability of high-quality data from various …

A dynamical approach, rather than the usual statistical approach, is taken to explore the
physical mechanisms underlying the nonlinear transfer of energy, the dam** of the …

The accretion flow around the Galactic Centre black hole Sagittarius A*(Sgr A*) is expected
to have an electron temperature that is distinct from the ion temperature, due to weak …

Simple assumptions made regarding electron thermodynamics often limit the extent to which
general relativistic magnetohydrodynamic (GRMHD) simulations can be applied to …

Hot collisionless accretion flows, such as the one in Sgr A* at our Galactic center, provide a
unique setting for the investigation of magnetic reconnection. Here protons are …

While observations have suggested that power-law electron energy spectra are a common
outcome of strong energy release during magnetic reconnection, eg, in solar flares, kinetic …

We calculate the radiative properties of Sagittarius A*–spectral energy distribution, variability
and radio-infrared images–using the first 3D, physically motivated black hole accretion …

Magnetic reconnection is an important driver of energetic particles in many astrophysical
phenomena. Using kinetic particle-in-cell simulations, we explore the impact of three …

The physical foundations of the dissipation of energy and the associated heating in weakly
collisional plasmas are poorly understood. Here, we compare and contrast several …

We calculate the disruption scale, when this range exists. Such a steep 'transition range'is
sometimes observed in short intervals of solar-wind turbulence. The onset of collisionless …
