The dawn of the gravitational-wave (GW) era has sparked a greatly renewed interest into possible links between sources of high-energy radiation and GWs. The most luminous high-energy sources-gamma-ray bursts (GRBs)-have long been considered as very likely sources of GWs, particularly from short-duration GRBs, which are thought to originate from the merger of two compact objects such as binary neutron stars and a neutron star-black hole binary. In this paper, we discuss: (i) the high-energy emission from short-duration GRBs; (ii) what other sources of high-energy radiation may be observed from binary mergers; and (iii) how searches for high-energy electromagnetic counterparts to GW events are performed with current space facilities. While current high-energy facilities, such as Swift and Fermi, play a crucial role in the search for electromagnetic counterparts, new space missions will greatly enhance our capabilities for joint observations. We discuss why such facilities, which incorporate new technology that enables very wide-field X-ray imaging, are required if we are to truly exploit the multi-messenger era.This article is part of a discussion meeting issue 'The promises of gravitational-wave astronomy'.
引力波（GW）时代的到来极大地激发了人们对高能辐射源与引力波之间可能联系的新兴趣。最明亮的高能源——伽马射线暴（GRBs）——长期以来一直被视为很有可能的引力波源，尤其是短持续时间的伽马射线暴，人们认为它们起源于两个致密天体的合并，比如双中子星以及中子星 - 黑洞双星。在本文中，我们将讨论：（i）短持续时间伽马射线暴的高能辐射；（ii）从双星合并中可能观测到的其他高能辐射源；以及（iii）如何利用当前的空间设施来搜寻引力波事件的高能电磁对应体。虽然目前的高能设施，如雨燕卫星（Swift）和费米卫星（Fermi），在搜寻电磁对应体方面发挥着关键作用，但新的太空任务将极大地提升我们进行联合观测的能力。我们将探讨，如果要真正利用多信使时代，为何需要这样采用了能实现极宽视场X射线成像新技术的设施。本文是“引力波天文学的前景”讨论会议文集的一部分。
