第一个引力波（GW）瞬变GW 150914的探测促使了在所有波长上进行广泛的后续观测活动。虽然没有进行专门的XMM-牛顿观测，但该卫星在正常运行期间通过了GW 150914错误区域。在这里，我们报告了GW事件发生两小时和两周后进行的卫星回转期间采集的数据的分析。我们的数据覆盖1.1和4.8 deg 2的最终GW本地化区域。在0.2-2 keV波段，没有发现与GW 150914对应的X射线，灵敏度低至6 × 10−13 erg cm−2 s−1。然而，这些观测结果显示了XMM-牛顿回转观测在寻找GW事件的电磁对应物方面的巨大潜力。为响应GW触发而执行的一系列相邻回转将花费1.5天来覆盖大多数典型GW可信区域。我们讨论了这种情况下，它的前景检测X射线对应的未来GW检测。
The detection of the first gravitational wave (GW) transient GW150914 prompted an extensive campaign of follow-up observations at all wavelengths. Although no dedicated XMM-Newton observations have been performed, the satellite passed through the GW150914 error region during normal operations. Here we report the analysis of the data taken during these satellite slews performed two hours and two weeks after the GW event. Our data cover 1.1 and 4.8 deg2 of the final GW localization region. No X-ray counterpart to GW150914 is found down to a sensitivity of 6 × 10−13 erg cm−2 s−1 in the 0.2–2 keV band. Nevertheless, these observations show the great potential of XMM-Newton slew observations for searching for the electromagnetic counterparts of GW events. A series of adjacent slews performed in response to a GW trigger would take ≲1.5 days to cover most of the typical GW credible region. We discuss this scenario and its prospects for detecting the X-ray counterpart of future GW detections.
