Microwave Polar Brightening and Its Connection to Polar Coronal Holes

The Astrophysical Journal
Polar brightening (PB) observed at microwave frequencies serves as an important probe to study the thermal and magnetic properties in the Sun’s polar regions.

Magneto-thermal Coupling and Coronal Heating in Solar Active Regions Inferred from Microwave Observations

The Astrophysical Journal
The solar corona is much hotter than the photosphere and chromosphere, but the physical mechanism responsible for heating the coronal plasma remains unidentified. The thermal microwave emission, which is produced in a strong magnetic field above sunspots,

IMPROVED RADIO MAPPING OF THE SUN [PDF]

1971-03-30Improved data processing has been applied to the T-shaped 3-cm radioheliograph at Toyokawa. Unwanted harmonics of the signal corresponding to the frequency range beyond the cut-off spatial frequency have been removed.

The Quiet Sun between 150 and 450 MHz : morphology and modeling

, 2011
We present results from quiet sun observations in the metric range. Solar images where obtained through rotational aperture synthesis at a number of frequencies, using the Nançay radioheliograph in its latest version, from 2004 to 2011.

Eruption of a high-latitude prominence observed by the Siberian Radioheliograph and space-borne telescopes: I. Torus and helical kink instabilities in CME development

Solar-Terrestrial Physics
The eruption of a large prominence and the resulting development of a coronal mass ejection (CME) were observed on June 12, 2023 by the Siberian Radioheliograph in microwaves up to heliocentric distances exceeding two solar radii, space-borne telescopes ...

The data format preprocessing system for Chinese spectral radioheliograph

, 2015
Chinese Spectral RadioHeliograph (CSRH) is a new generation of solar radio telescope which produces 0.1 megabytes raw observational data in every 3 milliseconds. The raw data with self-dened format must be converted to a standard scientic data for-mat to

Estimating the Total Energy Content in Escaping Accelerated Solar Electron Beams

The Astrophysical Journal
Quantifying the energy content of accelerated electron beams during solar eruptive events is a key outstanding objective that must be constrained to refine particle acceleration models and understand the electron component of space weather.
