Description
Weak solar radio bursts are associated with ubiquitous heating and particle acceleration activity in the solar corona. Since metrewave frequencies are sensitive to emission across coronal heights as a function of frequency, spectroscopic snapshot imaging facilitates tomographic exploration these active phenomena. The advent of simultaneous wideband high dynamic range imaging with MWA enabled the study of bust sites using spatially resolved dynamic spectra at sub-s and sub-MHz resolution. I will summarize some of the novel discoveries, insights and research avenues these studies have unveiled. This will include the discovery of ~s timescale quasi-periodic pulsations in burst source structure in tandem with its intensity - their properties and implications for local physical fields. I will also present our exploration of coronal turbulence in the inner corona.
