Parkes observations for project P1345 semester 2024OCTS_04

This proposal aims to obtain timing solutions and constrain burst rates and spin down properties of a sample of new rotating radio transients (RRATs) discovered with the ASKAP CRAFT Coherent upgrade (CRACO) system. In the last 6-months of commissioning, CRACO discovered and localised 10 new RRATs, identified by their sporadic pulses with dispersion measures (DM) consistent with Galactic objects.

We request 15h of Parkes time split into three 30min observations spanning 6-months for each target. This will allow us to constrain phase-coherent timing solutions given that we already have arcsec-precision interferometric localisations. Our main science goals are: 1) to measure their burst rates, periods, and spin-down properties;
2) to assess their nulling fraction and emission mechanism 3) to determine if the CRACO RRATs are different to the known RRATs population.
