GRB, FRB and Magnetar Triggered Searches for Gravitational Waves in Advanced LIGO, Advanced Virgo and KAGRA's Third and Fourth Observing Runs

This talk will present a summary of the results of and plans for searches for gravitational waves associated with gamma-ray bursts, fast radio bursts, and magnetars in the third observing and fourth observing runs of Advanced LIGO and Advanced Virgo and KAGRA. The third observing run concluded on Mar 27, 2020, and the fourth observing run will be starting close to the time of the April APS meeting, 2023. This talk will cover the current status of the efforts to conduct both targeted template-based and unmodeled searches for gravitational waves in Advanced LIGO, Advanced Virgo and KAGRA data. This will include both the high-latency, deep analyses, and efforts that are being made to bring a lightweight, rapid-followup analysis into production. The impact of the discovery of a kilonova associated with GRB 211211A on upcoming search plans will also be highlighted.
