Chromospheric magnetic field extrapolations reveal the flux-rope configuration of a solar filament

Robert Jarolim, João M. da Silva Santos, Matthias Rempel +5

Solar eruptions are powered by the release of magnetic energy stored in the lower solar atmosphere, but the pre-eruptive magnetic configuration of filament channels remains difficu…

SuNeRF-CME: Physics-Informed Neural Radiance Fields for Tomographic Reconstruction of Coronal Mass Ejections

Robert Jarolim, Martin Sanner, Chia-Man Hung +8

Coronagraphic observations enable direct monitoring of coronal mass ejections (CMEs) through scattered light from free electrons, but determining the 3D plasma distribution from 2D…

Improving Solar Flare Soft X-ray Classification With FOXES: A Framework For Operational X-ray Emission Synthesis

Griffin T. Goodwin, Alison J. March, Jayant Biradar +5

The Geostationary Operational Environmental Satellite (GOES) solar soft X-ray (SXR) irradiance in the 1-8Ã wavelength range is a long-standing measure of solar activity, used to de…
