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 […]

Tackling the Unique Challenges of Low-frequency Solar Polarimetry with the Square Kilometre Array Low Precursor: The Algorithm by Devojyoti Kansabanik et al

August 23, 2022

The solar corona comprises hot magnetized plasma. Coronal magnetic fields are well known to be one of the crucial parameters determining the physics of the solar corona and are vital drivers of Space Weather. Despite the fact that the importance of coronal magnetic fields has been recognised for a long, in practice, they remain rather hard to measure. The polarization properties of coronal emission at low radio frequencies can, in […]

Solar Physics with the Square Kilometre Array by A. Nindos et al.*

August 13, 2019

Although solar physics is one of the most mature branches of astrophysics, the Sun confronts us with a large number of outstanding problems that are fundamental in nature.  These problems include the determination of the structure and dynamics of the solar atmosphere, the magnetic field evolution in the chromosphere and corona, coronal heating, the physics of impulsive energy release, energetic particle acceleration and transport, the physics of coronal mass ejections […]
