Abstract:

I will present the results from the search for gravitational waves associated with Fast-Radio Bursts (FRBs) detected by the CHIME/FRB experiment during the LIGO-Virgo Observing Run O3a, from 1 April 2019 15:00 UTC - 1 October 2019 15:00 UTC. We have used both a generic gravitational wave transient search and a modelled search targeting coalescing binary systems. Several source types and morphologies were used during the searches. Assuming inferred FRB distances, we compare lower bounds on the GW detection distances and present upper limits on the possible energies emitted by gravitational waves for a range of transient models. I will also describe the status of the LIGO-Virgo-Kagra O3b search for gravitational wave counterparts to CHIME/FRB data. Finally, I will discuss preparations for the O4 LIGO-Virgo-Kagra Observation runs and the constraints that could be set by future joint GW/FRB searches.
