Coronal structures observed at metric wavelengths with the Nançay radioheliograph
, 1985 We present and discuss two-dimensional maps of the Sun at 169 MHz, obtained with the Nançay radioheliograph used as an Earth rotation aperture synthesis instrument. The maps have been computed on the basis of about 6 hr of one-dimensional observations by

Electron acceleration and transport in the 2023-03-06 solar flare
Frontiers in Astronomy and Space SciencesWe 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 PhysicsFor 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 JournalThe 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 ...
