Parkes observations for project P1409 semester 2026APRS_01

To investigate the physical origin and local environment of the repeating fast radio burst FRB 20230607A, which exhibits an exceptionally high rotation measure, we propose to observe this repeater with 24-hour observations using the Ultra-Wideband Low-frequency (UWL) receiver of the Parkes radio telescope (Murriyang). This proposal aims to monitor the secular evolution of the Faraday Rotation Measure, studying the cause of its low linear polarization, and resolve the specro-polarimetric structure of repeat bursts. The possible findings are critical to unveiling the extreme magnetized environment of the source, understanding emission mechanisms and propagation effects, and thereby shedding light on the physics origin(s) of repeating fast radio bursts.
