Odd Radio Circles Modeled by Shock-bubble Interactions

The Astrophysical Journal
The physical nature and origins of the newly discovered class of Odd Radio Circles (ORCs) remain unclear. We investigate a model whereby ORCs are synchrotron-emitting vortex rings formed by the Richtmyer–Meshkov instability (RMI) when a shock interacts ...

A cylindrical magnetohydrodynamic arbitrary Lagrangian Eulerian code [PDF]

Arbitrary Lagrangian Eulerian methods are methods which seek to take advantage of the strengths of Eulerian and Lagrangian methods, whilst circumventing the weaknesses.

Magneto-hydrodynamical nonlinear simulations of magnetically confined plasmas using smooth particle hydrodynamics (SPH)

, 2019
The successful application of techniques inspired in Smoothed Particle Hydrodynamics (SPH) to magnetohydrodynamical (MHD) nonlinear simulations of magnetically confined plasmas requires the previous solution to a number of challenging issues that are ...

The Evolution of Substructure during Star Cluster Assembly

The Astrophysical Journal
Star cluster formation and assembly occur inside filamentary and turbulent molecular clouds, which imprint both spatial and kinematic substructure on the young cluster.

Magnetic Flux Plays an Important Role during a Black Hole X-Ray Binary Outburst in Radiative Two-temperature General Relativistic Magnetohydrodynamic Simulations

The Astrophysical Journal
Black hole (Bh) X-ray binaries cycle through different spectral states of accretion over the course of months to years. Although persistent changes in the Bh mass accretion rate are generally recognized as the most important component of state ...

Cosmic-Ray Feedback on Bistable Interstellar Medium Turbulence

The Astrophysical Journal
While cosmic rays ( E ≳ 1 GeV) are well coupled to a galaxy’s interstellar medium (ISM) at scales of L > 100 pc, adjusting stratification and driving outflows, their impact on small scales is less clear.

Constrained Simulations of the Magnetic Field in the Local Supercluster and the Propagation of UHECR

, 2003
Magnetic fields (MF) in the Local Supercluster (LSC) of galaxies may have profound consequences for the propagation of Ultra High Energy Cosmic Rays (UHECR). Faraday rotations measurements provide some informations about MF in compact clusters.

Forming Prominences Accounting for Partial Ionization Effects

The Astrophysical Journal
One of the most striking structures in the solar atmosphere are prominences, predominantly coronal structures, with thermodynamic conditions that vary from chromospheric internally to the corona that surrounds them.
