Particle Acceleration and Magnetic Field Amplification by Relativistic Shocks in Inhomogeneous Media [PDF]
Particle acceleration and magnetic field amplification in relativistic shocks propagating in inhomogeneous media are investigated by three-dimensional magnetohydrodynamical (MHD) simulations and test-particle simulations.

On the Evolution and Observational Signatures of Cosmic Ray Electrons in Magnetohydrodynamical Simulations [PDF]
Cosmic ray (CR) electrons are ubiquitous in the universe and reveal key insights into the non-thermal physics. Their synchrotron radiation, bremsstrahlung, and inverse Compton emission shed light on the interstellar medium, on galaxies and galactic ...

A magnetohydrodynamical model for the formation of episodic jets [PDF]
Episodic ejection of plasma blobs has been observed in many black hole systems. While steady, continuous jets are believed to be associated with large-scale open magnetic fields, what causes the episodic ejection of blobs remains unclear. Here by analogy

Global simulations of galactic dynamo driven by cosmic-rays and exploding magnetized stars [PDF]
We conduct global galactic--scale magnetohydrodynamical (MHD) simulations of the cosmic--ray driven dynamo. We assume that exploding stars deposit small--scale, randomly oriented, dipolar magnetic fields into the differentially rotating ISM, together ...

The Formation of Star-forming Disks in the TNG50 Simulation
We investigate the disk formation process in the TNG50 simulation, examining the profiles of SFR surface density (Σ _SFR ), gas inflow and outflow, and the evolution of the angular momentum of inflowing gas particles.

Plasmoid identification and statistics in two-dimensional Harris sheet and GRMHD simulations [PDF]
Magnetic reconnection is a ubiquitous phenomenon for magnetized plasmas and leads to the rapid reconfiguration of magnetic field lines. During reconnection events, plasma is heated and accelerated until the magnetic field lines enclose and capture the ...

Outlook on Magnetohydrodynamical Turbulence and Its Astrophysical Implications
Magnetohydrodynamical (MHD) turbulence is ubiquitous in magnetized astrophysical plasmas, and it radically changes a great variety of astrophysical processes.
