Solar flares are one of the most violent and energetic space weather events that are known to cause various adverse effects on the Earth. One of the major problems that must be solved to understand flares and to be able to predict their magnitudes is how the particles in the solar atmosphere are accelerated after the magnetic reconnection. One way to help solve this problem is to investigate the properties of the high energy electrons produced during the flare impulsive phase, observed in the hard X-ray (HXR) and microwave (MW). The two emissions are considered to be produced by a “common population” of the electrons, but some studies have also reported temporal, spatial, and energy discrepancies between them, challenging the widely-used notion. In order to truly understand the relationship between the two emissions, high-cadence observations must be made simultaneously in two wavelengths, both temporally and spatially, and the spectral inversion must also be spatially-resolved and done in a realistic magnetic field geometry.
