Description

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 from magnetic neutron stars. The high radio brightness and short activity window of the first discovery challenges us to look for fainter examples, in the hopes of elucidating the properties of the full population. This year, we ran a monitoring campaign of the Galactic Plane, with the explicit goal of detecting new transients. The campaign was highly successful, and in this talk I will outline some of the new discoveries, and what this tells us about this intriguing new class of sources.
