New Instrument in Solar Flare Detection: A 50–55 GHz Millimeter-Wave Radiometer Spectrometer by X. Xu et al.

November 25, 2025

Solar flares, among the most intense explosive phenomena in the solar atmosphere, release vast amounts of energy in a short period, resulting in enhanced electromagnetic radiation across multiple bands. These events pose significant threats to Earth’s space environment and human activities in space. High-energy electrons accelerated during flares emit millimeter-wave radiation through gyrosynchrotron radiation, providing unique insights into the underlying magnetic fields and energy release processes (Fleishman et al 2018).

Multispacecraft Analysis and Modeling of Type III Radio Burst Exciter Deceleration in Inhomogeneous Heliospheric Plasma F. Azzolini et al.

November 11, 2025

Electron beams accelerated in solar flares and escaping from the Sun along open magnetic field lines can trigger intense radio emissions known as type III solar radio bursts. However, the propagation dynamics of these electrons is still poorly understood and observationally constrained (Dulk et al 1987, Krupar et al 2015). Historically, single-spacecraft measurements have suggested deceleration but suffered from large uncertainties due to unknown source position. By leveraging four spacecraft […]
