Black Hole Flares: Ejection of Accreted Magnetic Flux through 3D Plasmoid-mediated Reconnection [PDF]
Astrophysical Journal Letters, 2021 Magnetic reconnection can power bright, rapid flares originating from the inner magnetosphere of accreting black holes. We conduct extremely high-resolution (5376 × 2304 × 2304 cells) general-relativistic magnetohydrodynamics simulations, capturing ...

Magnetic reconnection in the era of exascale computing and multiscale experiments [PDF]
Nature Reviews Physics, 2022 Astrophysical plasmas have the remarkable ability to preserve magnetic topology, which inevitably gives rise to the accumulation of magnetic energy within stressed regions including current sheets. This stored energy is often released explosively through

Magnetic Reconnection and Associated Particle Acceleration in High-Energy Astrophysics [PDF]
Space Science Reviews, 2023 Magnetic reconnection occurs ubiquitously in the universe and is often invoked to explain fast energy release and particle acceleration in high-energy astrophysics.

First-principles theory of the rate of magnetic reconnection in magnetospheric and solar plasmas [PDF]
Communications Physics, 2022 The rate of magnetic reconnection is of the utmost importance in a variety of processes because it controls, for example, the rate energy is released in solar flares, the speed of the Dungey convection cycle in Earth’s magnetosphere, and the energy ...

A magnetic reconnection model for hot explosions in the cool atmosphere of the Sun [PDF]
Astronomy & Astrophysics, 2020 Context. Ultraviolet (UV) bursts and Ellerman bombs (EBs) are transient brightenings observed in the low solar atmospheres of emerging flux regions. Magnetic reconnection is believed to be the main mechanism leading to formation of the two activities ...

3D turbulent reconnection: Theory, tests, and astrophysical implications [PDF]
Physics of Plasmas, 2020 Magnetic reconnection, topological changes in magnetic fields, is a fundamental process in magnetized plasmas. It is associated with energy release in regions of magnetic field annihilation, but this is only one facet of this process. Astrophysical fluid

Magnetic Reconnection and Hot Spot Formation in Black Hole Accretion Disks [PDF]
Astrophysical Journal, 2020 Hot spots, or plasmoids, which form due to magnetic reconnection in current sheets, are conjectured to power frequent X-ray and near-infrared flares from Sgr A*, the black hole in the center of our Galaxy.
