This project will use the CRACO facility on ASKAP to discover new FRBs, pinpoint their locations to their host galaxies, and follow-up repeaters with large single dishes such as FAST and Murriyang. They will also explore new facilities such as the CRYOPAF at Parkes/Murriyang.
The first stage of the project will entail becoming familiar with the CRACO facility, and using observations of known pulsars to understand the efficiency of the FRB detection pipelines and possibly spotting faults in it. At present there seems to be a deficit of FRBs near the detection threshold.
In parallel, the student will examine the population of FRBs and via the use of simulations and observational constraints explore what their potential is for use in cosmology, in particular for the value of the Hubble constant.
When available (late 2025?), the student will explore data from the new CRYOPAF at the Parkes radio telescope for discovering FRBs at high redshifts. The new CRYOPAF will have 4x the field of view and double the bandwidth of the High Time Resolution Universe survey instrument, and should discover FRBs ~10x as often, if not contaminated by interference.
Parkes/Murriyang has proven to be a valuable facility for detecting repeat bursts from repeating FRBs. As FRBs are discovered that appear to have band-limited or sad-trombone features, these will be pursued by Parkes and if necessary, the MeerKAT radio telescope
