Turbulence is ubiquitous in astrophysics. It radically changes many astrophysical
phenomena, in particular, the propagation and acceleration of cosmic rays. We present the …

Relativistic jets are associated with extreme astrophysical phenomena, like the core
collapse of massive stars in gamma-ray bursts (GRBs) and the accretion on to supermassive …

Particle acceleration in solar flares remains an outstanding problem in plasma physics and
space science. While the observed particle energies and timescales can perhaps be …

The origins of the various outbursts of hard X-rays from magnetars (highly magnetized
neutron stars) are still unknown. We identify instabilities in relativistic magnetospheres that …

Magnetic fields can change their topology through a process known as magnetic
reconnection. This process in not only important for understanding the origin and evolution …

In this Letter we analyze the energy distribution evolution of test particles injected in three
dimensional (3D) magnetohydrodynamic (MHD) simulations of different magnetic …

We study the evolution of kink instability in a force-free, nonrotating plasma column of high
magnetization. The main dissipation mechanism is identified as reconnection of magnetic …

Fast magnetic reconnection can occur in different astrophysical sources, producing flare-like
emission and particle acceleration. Currently, this process is being studied as an efficient …

We review the current literature on the formation of coherent structures (CoSs) in strongly
turbulent 3D magnetized plasmas. CoSs [Current Sheets (CS), magnetic filaments, large …

Context. Twisted coronal loops should be ubiquitous in the solar corona. Twisted magnetic
fields contain excess magnetic energy, which can be released during magnetic …
