Parkes observations for project P1101 semester 2024APRS_03

We propose to continue our fortnightly monitoring of a very active repeater, FRB 20190520B, with the Parkes UWL system. Our current observations show that FRB 20190520B is not only the most active FRB that can be observed with Parkes, but also shows extreme rotation measure (RM) and dispersion measure (DM) evolution and unique behavior at 2 to 3 GHz frequency. This makes UWL the ideal instrument to carry out in-depth studies of this repeating FRB. With this program, we expect to detect a large sample of bursts from FRB 20190520B, and in collaboration with FAST and GBT, we will study its local environment, emission properties, fluence distributions, and polarisation properties over an extremely wide bandwidth with high sensitivity.
