论文摘要
引力波和高能中微子事件的电磁观测对于理解其天体物理来源的物理学至关重要。 X射线对应物在研究系统中的射流物理学，流出能量和粒子加速机制方面特别有用。我们介绍了Neil Gehrels Swift天文台及时搜索与关节重力波和高能中微子重合事件的X射线对应物发生在第三次观察Ligo/处女座期间发生的事件。 Swift观察到，三个相当大的（P值<1％）关节重力波和高能中微子共同的警报之间的重力波和中微子误差区域之间的重叠，这是由Icecube Neutrino Pervintor在Ligo/Pirgo Gress attriation Wave Prave Public Public Public Public Public Public public触发后实时产生的。这些搜索并未将任何X射线对应物与任何关节重力波和高能中微子重合事件相关联，但是，这些警报的随访显着改善了涵盖重力波天空图和中微子之间中微子之间区域之间区域的平铺技术，从而为未来的潜在发现准备了实时发现系统。我们将讨论每个后续过程的详细信息，每个搜索的结果以及未来搜索的计划。
Electromagnetic observations of gravitational wave and high-energy neutrino events are crucial in understanding the physics of their astrophysical sources. X-ray counterparts are especially useful in studying the physics of the jet, the energy of the outflow, and the particle acceleration mechanisms in the system. We present the Neil Gehrels Swift Observatory prompt searches for X-ray counterparts to the joint gravitational wave and high-energy neutrino coincident events that happened during the third observing run of LIGO/Virgo. Swift observed the overlap between gravitational wave and neutrino error regions for three of the considerable (p-value < 1%) joint gravitational wave and high-energy neutrino coincident alerts, which were generated by the IceCube Neutrino Observatory in realtime after triggering by the LIGO/Virgo gravitational wave public alerts. The searches did not associate any X-ray counterparts to any of the joint gravitational wave and high-energy neutrino coincident events, however, the follow-up of these alerts significantly improved the tiling techniques covering regions between the gravitational wave sky maps and neutrino's error regions, making the realtime system ready for the future potential discoveries. We will discuss the details of each follow-up procedure, the results of each search, and the plans for future searches.
