Parkes observations for project P1281 semester 2024OCTS_13

The physical origin of fast radio bursts (FRBs) has been hotly debated over the past decade until the discovery of bright radio bursts from the Galactic magnetar in 2020. The discovery of galactic FRBs has demonstrated that at least some faint FRBs can originate from normal magnetars. So far, only two active FRB repeaters are confirmed to be associated with persistent radio sources, which are normally interpreted as magnetar wind nebulae by theorists. From the most recent observations with the FAST and Parkes telescopes, we observed a particular radio source, VT 1137-0337, and we found several suspicious short-duration single pulse candidates whose dispersion measurements were very close. Notably, the signal found in the Parkes UWL data has a typical pulse width of 1 ms and exhibits an apparent broadband feature. We strongly request continuing to monitor this source with the Parkes UWL receiver, aiming to detect a significant FRB and directly reveal the nature of the active FRB repeaters.
