论文摘要
超X射线源（ULX）是极端的X射线二进制物，在10^39 Erg/s以上闪闪发光，在大多数情况下，由于超级 - 埃德丁顿（Super-Eddington）积聚到中子星上，并在其埃德丁顿（Eddington）限制的限制上积聚了恒星的黑洞。在发现相干搏动，回旋线和强大的风之后，就可以理解这一点。由于XMM-Newton上的高分辨率X射线光谱仪，后者有可能。由于其相对论速度（0.1-0.3 C），ULX风具有大量的功率，并且能够显着影响周围的介质，可能会产生观察到的100个PC ULX Superbubbles，并限制可以到达中央吸积的物质。因此，对ULX风的研究是典型的理解1）紧凑的物体会积聚多少速度，以及2）它们对周围介质的反馈有多强。这对于了解超大质量黑洞的生长也很重要。在这里，我们提供了有关这种现象学的概述，重点介绍了一些最近令人兴奋的结果，并展示了Xrism，Extp和Athena等未来任务将如何提高我们的理解。
Ultraluminous X-ray sources (ULXs) are extreme X-ray binaries shining above 10^39 erg/s, in most cases as a consequence of super-Eddington accretion onto neutron stars and stellar-mass black holes accreting above their Eddington limit. This was understood after the discovery of coherent pulsations, cyclotron lines and powerful winds. The latter was possible thanks to the high-resolution X-ray spectrometers aboard XMM-Newton. ULX winds carry a huge amount of power owing to their relativistic speeds (0.1-0.3 c) and are able to significantly affect the surrounding medium, likely producing the observed 100 pc ULX superbubbles, and limit the amount of matter that can reach the central accretor. The study of ULX winds is therefore quintessential to understand 1) how much and how fast can matter be accreted by compact objects and 2) how strong is their feedback onto the surrounding medium. This is also relevant to understand supermassive black holes growth. Here we provide an overview on this phenomenology, highlight some recent, exciting results and show how future missions such as XRISM, eXTP and ATHENA will improve our understanding.
