A Genetic Algorithm to Model Solar Radio Active Regions From 3D Magnetic Field Extrapolations

Frontiers in Astronomy and Space Sciences, 2022
In recent decades our understanding of solar active regions (ARs) has improved substantially due to observations made with better angular resolution and wider spectral coverage.

Electron acceleration and transport in the 2023-03-06 solar flare

Frontiers in Astronomy and Space Sciences
We investigated in detail the M5.8 class solar flare that occurred on 2023-03-06. This flare was one of the first strong flares observed by the Siberian Radioheliograph in the microwave range and the Advanced Space-based Solar Observatory in the X-ray ...

Correction for pointing errors of Siberian Radioheliograph antennas

Solar-Terrestrial Physics
For radio interferometers, antenna pointing accuracy is critical, as deviations in the direction of the beam from the source not only reduce the signal level, but also lead to incorrect measurements of visibility phases.

Radio Signature of Higher Atmospheric Meridional Flow and Implications for Magnetic Trees in the Sun

The Astrophysical Journal
The coupling between plasma flows and magnetic fields in the solar atmosphere governs the transport of angular momentum and the redistribution of magnetic flux, yet its manifestation in the magnetically dominated upper chromosphere remains uncertain ...
