The magnetar SGR 1935+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 ≤1 s) we derive 50% (90%) upper limits of 1048 (1049) erg for GWs at 300 Hz and 1049 (1050) erg at 2 kHz, 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 10 s. These represent the strictest upper limits on concurrent GW emission from FRBs.

使用 GEO600 搜索 SGR 1935+2154 与快速射电暴重合的引力波



磁星 SGR 1935+2154 是银河系唯一已知的快速射电暴 (FRB) 源。在 LIGO、Virgo 和 KAGRA Collaborative 的 O3 观测运行结束后,加拿大氢强度测绘实验 (CHIME)/FRB 和瞬态天文射电发射巡天于 2 于 2020 年 4 月首次检测到来自 SGR 1935+2154 的 FRB。在这里,我们分析了来自 GEO600 探测器的四个引力波 (GW) 周期数据,这些数据与 CHIME/FRB 检测到的四个 FRB 活动周期相吻合,以及 NICER 和 NuSTAR 检测到的接近其中一个 FRB 时间的 X 射线毛刺和 X 射线暴。我们没有检测到任何事件中任何显著的 GW 排放。相反,使用短持续时间的 GW 搜索(对于突发 ≤1 s),我们得出 300 Hz 时 GW 的 1048 (1049) erg 的 50% (90%) 上限和 2 kHz 时的 1049 (1050) erg,并将 GW 与无线电能量的比限制为 ≤1014−1016。我们还通过长时间搜索持续时间在 1 到 10 秒之间的突发来得出上限。这些代表了 FRB 并发 GW 排放的最严格上限。
