A new methodology for inferring the plasma conditions in solar flare energetic electron source regions from in situ electron energy spectra
Samuel Carter, Natasha L. S. Jeffrey, Robert T. Wicks +1
The conditions within solar flares that lead to efficient electron acceleration are not well constrained. It is not clear whether the populations accelerated out into the heliosphe…
Multi-wavelength observations of substructures in solar flare ribbons
Vishal Singh, Eamon Scullion, Gert J. J. Botha +6
Solar flare ribbons are extensive brightenings in the chromosphere during flares, often showing fine scale structuring that reflects the underlying energy release. Using high caden…
Transport of electrons in tangled magnetic fields
Daniel Verscharen, Natasha Jeffrey, Anton Artemyev +6
Cosmic magnetic fields are typically inhomogeneous and often highly tangled due to large-scale plasma flows, turbulence, and instabilities. If the variations in the magnetic field…
Constraining turbulent solar flare acceleration regions by connecting kinetic modeling and X-ray observations
Morgan Stores, Natasha Jeffrey, Ewan Dickson +2
Spatially-resolved X-ray observations are the key to understanding electron acceleration in solar flares. Currently, the underlying processes that efficiently energize solar flare…
Time-dependent Turbulent Electron Acceleration and Transport in Solar Flares
Luiz A. C. A. Schiavo, Natasha L. S. Jeffrey, Gert J. J. Botha +1
Solar flares are explosive releases of magnetic energy stored in the solar corona, driven by magnetic reconnection. These events accelerate electrons, generating hard X-ray emissio…
Tracing the Heliospheric Magnetic Field via Anisotropic Radio-Wave Scattering
Daniel L. Clarkson, Eduard P. Kontar, Nicolina Chrysaphi +4
Astrophysical radio sources are embedded in turbulent magnetised environments. In the 1 MHz sky, solar radio bursts are the brightest sources, produced by electrons travelling alon…
