我们用全天X射线图像监视器(MAXI)搜索了引力波(GW)事件GW150914的X射线候选物。Maxi从GW事件发生后4 分钟观察到GW事件GW150914的误差区，并在25 分钟内覆盖了约90%的误差区。在GW误差区内，从1 S到4 d的时间尺度没有明显的时间变化。与GW事件相关的3个 σ辐射上限分别为9.5x×10 −10，2.3x×10−10和0.8x×10−10erg cm−2s−1，时间尺度分别为∼1000 S，1 d和10 d。如果GW事件与伽马暴050709这样的短伽马射线暴有关，MAXI将能够探测到源发出的X射线。
We searched for X-ray candidates for the gravitational wave (GW) event GW150914 with Monitor of All-sky X-ray Image (MAXI). MAXI observed the error region of the GW event GW150914 from 4 min after the event and covered about 90% of the error region in 25 min. No significant time variations on timescales of 1 s to 4 d were found in the GW error region. The 3 σ upper limits for the X-ray emission associated with the GW event in 2–20 keV were 9.5 × 10−10, 2.3 × 10−10, and 0.8 × 10−10erg cm−2s−1for the time scales of ∼1000 s, 1 d, and 10 d, respectively. If GW events are associated with short gamma-ray bursts like GRB 050709, MAXI will be able to detect X-ray emissions from the source.
