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...
One of the most exciting discoveries in MWA data has been an unusual periodic radio transient, repeating every 18.18 minutes, with the discovery published in Nature earlier this year. The source's long period makes it challenging to explain the radio emission with conventional theories of pulsar emission, yet the high polarisation and pulse morphologies are similar to what would be expected...
