First Detailed MeerKAT Imaging Spectroscopy of a Solar Flare
Yingjie Luo, Eduard P. Kontar, Roelf Du Toit Strauss +5
Radio observations provide powerful diagnostics of energy release, particle acceleration, and transport processes in solar flares. However, despite recent progress in radio interfe…

Energy-Containing Electrons in Solar Flares: Improving Hard X-Ray and EUV Diagnostics
Yingjie Luo, Eduard P. Kontar, Debesh Bhattacharjee
Solar flares effectively accelerate particles to non-thermal energies. These accelerated electrons are responsible for energy transport and subsequent emissions in HXR, radio, and…

Total Power and Low-energy Cut-off Time Evolution of Solar Flare Accelerated Electrons Using X-Ray Observations and Warm-Target Model
Debesh Bhattacharjee, Eduard P. Kontar, Yingjie Luo
A primary characteristic of solar flares is the efficient acceleration of electrons to nonthermal deka-keV energies. While hard X-Ray (HXR) observation of bremsstrahlung emission s…
