Abstract : | Low radio frequencies (< 300 MHz) have long been known to provide diagnostics of the solar
corona which are complementary to those available from other wavebands. High dynamic range
and high fidelity imaging of the radio Sun, required to access much of this science, is however
extremely challenging. Only comparatively recently the instrumental capabilities and imaging
algorithms have caught up with these exacting demands. This talk will present a review of the
progress made in the areas of instrumentation and algorithms in the past few years, and new
science results enabled from this work. They span a large range - from tantalising evidence for
nanoflare based coronal heating to estimating magnetic fields entrained in coronal mass
ejections, and discovering previously unknown characteristics of solar radio bursts known since
1950s. Not only is this work marking remarkable progress towards realising the potential of solar
radio observations, it is also uncovering unanticipated new features in solar emissions, forcing a
rethink of the conventional wisdom. I will place this work in context of the Square Kilometre
Array Observatory, currently under construction and expected to become available by 2028 and
also share our plans for the near term. |
