Abstract:
Active solar radio emissions usually arise from processes complementary to those giving rise to emissions at X-rays, EUV and optical bands. Additionally, the polarization of solar radio emissions not only carries detailed information about the intrinsic emission mechanism but also the strength and topology of the coronal magnetic fields. As this emission traverses the coronal medium, it gets imprinted with signatures of the turbulent birefringent magnetized coronal plasma. Radio observations also provide one of the few means to probe the vast coronal and heliospheric medium via studies of the propagation effects. In practice, however, a mix of instrumental and algorithmic limitations has kept the promise of solar radio observations from being realized. This is now changing. Several new-generation radio interferometers have recently become available, and more are expected in the near future. These are the many precursors and pathfinders of the Square Kilometre Array Observatory (SKAO) and the SKAO itself. The vastly improved observational abilities of these instruments are very well aligned with the needs of solar and heliospheric physics. For over a decade now, we have devoted considerable effort towards enabling solar and heliospheric science with these instruments and our efforts have led to solar radio images with unprecedented fidelity and dynamic range at fine spectral and temporal resolutions. We have used this capability to investigate a diverse set of aspects from coronal heating and space weather to the quiescent Sun and coronal angular broadening. This talk will showcase some example science areas where considerable progress has been made, share the status and near-term plans for radio solar and heliospheric observations with these new-generation instruments and the science opportunities they present.
