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…
Neural blind deconvolution to reconstruct high-resolution ground-based solar observations
Christoph Schirninger, Robert Jarolim, Astrid M. Veronig +2
Ground-based solar observations enable unprecedented spatial, spectral, and temporal resolution of the lower solar atmosphere, yet Earths turbulent atmosphere imposes significant l…
Multi-height probing of horizontal flows in the solar photosphere
Teodor KostiÄ, Ivan MiliÄ, Matthias Rempel +4
We tested whether simultaneous spectropolarimetric imaging in two magnetically sensitive optical spectral lines, which probe two different layers of the solar atmosphere (the photo…
PINN ME: A Physics-Informed Neural Network Framework for Accurate Milne-Eddington Inversions of Solar Magnetic Fields
Robert Jarolim, Momchil E. Molnar, Benoit Tremblay +2
Spectropolarimetric inversions of solar observations are fundamental for the estimation of the magnetic field in the solar atmosphere. However, instrumental noise, computational re…
