论文摘要
欧洲航天局正在研究三个大型任务在30年代的十年中，旨在调查宇宙中最有活力和最暴力的现象。 $ Athena $有望研究锁定在其形成时代的大规模结构中的重子的物理状况，并产生准确的人口普查，以使超大型黑洞降低到电源时代。丽莎将向迄今未探索的MHz制度扩展狩猎引力波（GW）事件。我们在本文中讨论了他们的同时操作可以产生的科学，并提出可能的$ athena $观察策略。我们专注于超质量（m $ \ lyssim10^7 \ rm m _ {\ odot} $）黑洞合并（smbhms），可能可访问$ achena $ to $ z \ sim2 $。同时测量其电磁（EM）和GW信号可能会在天体物理学，基本物理学和宇宙学领域中实现独特的实验，例如流体流动流的磁流动力学在快速变化的时空中，在Active Actival and Active coturic and Active copurei and nucuri suturi and nucuri和suturie的速度中，以及GW的速度。实现这些突破性结果的关键将是LISA的能力，可以找到一个具有可比性的错误盒，或者比$ Athena $ ade Field Imager（$ \ simeq0.4 \，$ deg $^2 $）和$ ATHENA $ ATHENA $ $ ATHENA $ CABLICATIO的能力在Pussem阶段和Post-Post-Merser阶段的源源的能力。这两个观察者将共同开放，原则上，对SMBHM的真正并发EM和GW研究的令人兴奋的可能性
The European Space Agency is studying two large-class missions bound to operate in the decade of the 30s, and aiming at investigating the most energetic and violent phenomena in the Universe. $Athena$ is poised to study the physical conditions of baryons locked in large-scale structures from the epoch of their formation, as well as to yield an accurate census of accreting super-massive black holes down to the epoch of reionization; LISA will extend the hunt for Gravitational Wave (GW) events to the hitherto unexplored mHz regime. We discuss in this paper the science that their concurrent operation could yield, and present possible $Athena$ observational strategies. We focus on Super-Massive (M$\lesssim10^7\rm M_{\odot}$) Black Hole Mergers (SMBHMs), potentially accessible to $Athena$ up to $z\sim2$. The simultaneous measurement of their electro-magnetic (EM) and GW signals may enable unique experiments in the domains of astrophysics, fundamental physics, and cosmography, such as the magneto-hydrodynamics of fluid flows in a rapidly variable space-time, the formation of coronae and jets in Active Galactic Nuclei, and the measurement of the speed of GW, among others. Key to achieve these breakthrough results will be the LISA capability of locating a SMBHM event with an error box comparable to, or better than the field-of-view of the $Athena$ Wide Field Imager ($\simeq0.4\,$deg$^2$) and $Athena$ capability to slew fast to detect the source during the inspiral phase and the post-merger phase. Together, the two observatories will open in principle the exciting possibility of truly concurrent EM and GW studies of the SMBHMs
