Solar, Heliospheric and Ionospheric Physics: Pathfinders, Precursors and SKAO Perspective
Pietro Zucca, Rohit Sharma, Divya Oberoi +5
The Solar, Heliospheric and Ionospheric (SHI) Physics Science Working Group of the Square Kilometre Array Observatory (SKAO) addresses the full chain of plasma processes linking th…
The SKA as a Probe of Heliospheric Turbulence and Radio-wave Propagation Effects
Nicolina Chrysaphi, Eduard P. Kontar, Hamish A. S. Reid +3
Density turbulence in the heliosphere can impact traversing radio photons originating from anywhere in the universe, leading to distortions of both the spectroscopic and imaging pr…
Unravelling the nonthermal emissions from the quiet solar corona with the SKA
Surajit Mondal, Divya Oberoi, Rohit Sharma +4
Investigation of the nonthermal emissions from the quiet solar corona has been rather limited. This primarily stems from the fact that the emission is expected to be quite weak and…
Radio Wave Propagation as a Probe of the Solar Corona and Solar Wind
K. Sasikumar Raja, Prasad Subramanian, Susanta Kumar Bisoi +3
Radio waves propagating through an inhomogeneous, turbulent medium such as the solar corona and solar wind become distorted, causing the initially plane wavefronts becomes corrugat…
