Noise maps of the Sun at radio wavelengths by TS Bastian et al. – Community of European Solar Radio Astronomers

The Sun is a powerful source of radio emissions, to the point that, unlike most celestial sources, this emission dominates the system noise of many radio telescopes. The noise resulting from these sources is called “own noise”. Two recent papers analyze self-noise in maps of the Sun at radio frequencies formed using Fourier synthesis imaging…
