A test suite for magnetohydrodynamical simulations
Astrophysical Journal, 1992 A collection is presented of MHD problems that will provide researchers who have interests in modeling MHD phenomena with a battery of tests (a 'test suite') for calibrating their numerical algorithms. Use of these tests will provide a common reference for comparison of different numerical MHD algorithms. The test suite includes both 1D and 2D problems.

Avalanches in magnetohydrodynamical simulations
Physical Review EScale invariance is a hallmark of many natural systems, including solar flares, where energy release spans a vast range of scales. Recent computational advances, at the level of both algorithmics and hardware, have enabled high-resolution magnetohydrodynamical (MHD) simulations to span multiple scales, offering new insights into magnetic energy ...

Inferring the Magnetic Field from the Rayleigh–Taylor Instability
The Astrophysical Journal, 2023 By extending the potential approach of Layzer and Goncharov to the magnetohydrodynamics equations, we find the nonlinear solutions to the single-mode Rayleigh–Taylor instability subjected to uniform magnetic fields at various inclinations. This allows us

Magnetohydrodynamic Simulations of the Supernova Remnant G1.9+0.3
The Astrophysical Journal, 2023 The youngest Galactic supernova remnant G1.9+0.3 shows a discrete feature between its radio and X-ray morphologies. The observed radio morphology features a single maximum in the north, while the X-ray observation shows two opposite “ears” on the east ...

Global MHD Simulations of the Time-dependent Corona
The Astrophysical Journal, 2023 We describe, test, and apply a technique to incorporate full-Sun, surface flux evolution into an MHD model of the global solar corona. Requiring only maps of the evolving surface flux, our method is similar to that of Lionello et al., but we introduce ...

On the Evolution and Observational Signatures of Cosmic Ray Electrons in Magnetohydrodynamical Simulations [PDF]
, 2020 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]
, 2009 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

Rotation in Event Horizon Telescope Movies
The Astrophysical Journal, 2023 The Event Horizon Telescope (EHT) has produced images of M87* and Sagittarius A*, and will soon produce time sequences of images, or movies. In anticipation of this, we describe a technique to measure the rotation rate, or pattern speed Ω _p , from ...
