MeerKAT imaging spectroscopy reveals multiple electron acceleration sites in a solar flare by Luo et al.

June 9, 2026

Solar flares are the most explosive energy-release events in the solar corona, leading to intense particle acceleration, plasma heating, and bulk plasma motions on short timescales. Core questions during solar flares remain unresolved, including how and where particle acceleration occurs, and how energized electrons propagate through coronal magnetic structures. Radio observations, due to their unique sensitivity to nonthermal and thermal electrons, serve as powerful diagnostics of electron dynamics and high-temperature […]

A Flare-related Decimetric Type-IV Radio Burst Induced by the X2 Radiation of Electron Cyclotron Maser Emission by Lv et al.

September 16, 2025

Decimetric broadband radio bursts (with frequencies of hundreds of MHz to a few GHz) have been observed from the Sun and other flaring stars. In the solar case, such bursts have been classified as the decimetric type-IV (t-IVdm) bursts. Their spectra often contain substantial fine structures, such as pulsations, spikes, and various absorption structures. This makes them distinct from their metric and centimetric counterparts. Due to the lack of imaging […]

Flare Accelerated Electron Transport in Type III Solar Radio Bursts: large-scale transport and super-diffusive beam expansion by E. P. Kontar et al.

January 21, 2025

Solar flares, the most powerful magnetic explosions in our solar system, are often accompanied by intense bursts of radio emission known as type III solar radio bursts. These bursts provide valuable clues about the acceleration and transport of energetic electrons in the Sun’s atmosphere and beyond. Understanding these bursts is not only crucial for solar physics but also for predicting space weather events that can disrupt our technological infrastructure. A […]

Data-constrained Solar Modeling with GX Simulator by G. Nita et al

August 8, 2023

In the dynamic realm of modern solar physics, where vast and diverse data sets challenge understanding, a critical need emerges for advanced data-constrained 3D modeling that combines photospheric magnetic fields measurements and a wide range of contextual electromagnetic radiation observations, which includes radio, X-ray, and extreme ultraviolet (EUV) emissions. Bridging all these available observational data constraints is imperative to create a comprehensive understanding of solar activity and phenomena. Addressing this […]

Imaging preflare broadband pulsations in the decimetric-metric wavelengths by Lv et al

July 4, 2023

Solar radio pulsations represent (quasi-)periodic or irregular short fluctuations observed from the radio flux curves or the dynamic spectra, in almost all wavelength ranges from metric to microwave (See the review by Nindos & Aurass 2007). They can be classified as broadband pulsations (BBPs) and narrowband pulsations (NBPs). Most earlier studies have focused on pulsations taking place during the impulsive or decay phases of solar flares. During the preflare stage, […]
