Abstract

The magnetar SGR1935+2154 is the only known Galactic source of fast radio bursts (FRBs). FRBs from SGR 1935 +2154 were first detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME)/FRB and the Survey for Transient Astronomical Radio Emission 2 in 2020 April, after the conclusion of the LIGO, Virgo, and KAGRA Collaborations’ O3 observing run. Here, we analyze four periods of gravitational wave (GW) data from the GEO600 detector coincident with four periods of FRB activity detected by CHIME/FRB, as well as X-ray glitches and X-ray bursts detected by NICER and NuSTAR close to the time of one of the FRBs. We do not detect any significant GW emission from any of the events. Instead, using a short-duration GW search (for bursts 1s) we derive 50% (90%) upper limits of 1048 (1049) erg for GWs at 300Hz and 1049 (1050) erg at 2kHz, and constrain the GW-to-radio energy ratio to 1014−1016. We also derive upper limits from a long-duration search for bursts with durations between 1 and 10s. These represent the strictest upper limits on concurrent GW emission from FRBs.
