Flare Kernels May be Smaller than You Think: Modelling the Radiative Response of Chromospheric Plasma Adjacent to a Solar Flare
Christopher M. J. Osborne, Lyndsay Fletcher
Numerical models of solar flares typically focus on the behaviour of directly-heated flare models, adopting magnetic field- aligned, plane-parallel methodologies. With high spatial…
On the Importance of Ca II Photoionisation by the Hydrogen Lyman Transitions in Solar Flare Models
Christopher M. J. Osborne, Petr Heinzel, Jana Kašparová +1
The forward fitting of solar flare observations with radiation-hydrodynamic simulations is a common technique for learning about energy deposition and atmospheric evolution during…
The Lightweaver Framework for NLTE Radiative Transfer in Python
Christopher M J Osborne, Ivan Milić
Tools for computing detailed optically thick spectral line profiles out of local thermodynamic equilibrium have always been focused on speed, due to the large computational effort…
Spectral deconvolution with deep learning: removing the effects of spectral PSF broadening
Momchil Molnar, Kevin Reardon, Christopher Osborne +1
We explore novel methods of recovering the original spectral line profiles from data obtained by instruments that sample those profiles with an extended or multipeaked spectral tra…
Thyr: A Volumetric Ray-Marching Tool for Simulating Microwave Emission
Christopher M. J. Osborne, Paulo J. A. Simões
Gyrosynchrotron radiation is produced by solar flares, and can be used to infer properties of the accelerated electrons and magnetic field of the flaring region. This microwave emi…
RADYNVERSION: Learning to Invert a Solar Flare Atmosphere with Invertible Neural Networks
Christopher M. J. Osborne, John A. Armstrong, Lyndsay Fletcher
During a solar flare, it is believed that reconnection takes place in the corona followed by fast energy transport to the chromosphere. The resulting intense heating strongly distu…
