We.se.rch for gravitational-wave.(GW) transie.ts associate. with fast radio bursts (FRBs) de.e.te. by the.Canadian Hydroge. Inte.sity Mapping e.pe.ime.t Fast Radio Burst Proje.t, during the.first part of the.third obse.ving run of Advance. LIGO and Advance. Virgo (2019 April 1 15:00 UTC-2019 Octobe. 1 15:00 UTC). Trigge.s from 22 FRBs we.e.analyze. with a se.rch that targe.s both binary ne.tron star (BNS) and ne.tron star-black hole.(NSBH) me.ge.s. A targe.e. se.rch for ge.e.ic GW transie.ts was conducte. on 40 FRBs. We.find no significant e.ide.ce.for a GW association in e.the. se.rch. Give. the.large.unce.taintie. in the.distance. of our FRB sample. we.are.unable.to e.clude.the.possibility of a GW association. Asse.sing the.volume.ric e.e.t rate. of both FRB and binary me.ge.s, an association is limite. to 15% of the.FRB population for BNS me.ge.s or 1% for NSBH me.ge.s. We.re.ort 90% confide.ce.lowe. bounds on the.distance.to e.ch FRB for a range.of GW proge.itor mode.s and se. uppe. limits on the.e.e.gy e.itte. through GWs for a range.of e.ission sce.arios. We.find value. of orde. 10⁵¹-10⁵⁷ e.g for mode.s with ce.tral GW fre.ue.cie. in the.range.70-3560 Hz. At the.se.sitivity of this se.rch, we.find the.e.limits to be.above.the.pre.icte. GW e.issions for the.mode.s conside.e.. We.also find no significant coincide.t de.e.tion of GWs with the.re.e.te., FRB 20200120e. which is the.close.t known e.tragalactic FRB. © 2023. The.Author(s).
