论文摘要
广播:X射线相关性的特征是在所有质量尺度上积聚黑洞的特征 - 从二进制系统中的恒星质量黑洞到为主动银河核供电的超质量黑洞 - 是支持积极的观察证据之一,这些证据是在积累过程中存在连接的最重要的观察证据之一,并且是叠加过程与串出销售超过的系统的连接。尽管最近的研究表明,相关性延伸至低亮度,但仅检测到少数恒星的黑洞,通常在静止期间只能获得上限(尤其是在无线电波长下)。最近,我们使用Meerkat射电望远镜和Swift X射线望远镜仪器在Neil Gehrels Swift天文台上获得了黑洞X射线二进制GX 339--4的检测,并探测了X射线相关性的下端。我们介绍了该规范黑洞XRB系统的较低的低速速率制度中增生和连接生成的JET的特性。
The radio:X-ray correlation that characterises accreting black holes at all mass scales - from stellar mass black holes in binary systems to super-massive black holes powering Active Galactic Nuclei - is one of the most important pieces of observational evidence supporting the existence of a connection between the accretion process and the generation of collimated outflows - or jets - in accreting systems. Although recent studies suggest that the correlation extends down to low luminosities, only a handful of stellar mass black holes have been clearly detected, and in general only upper limits (especially at radio wavelengths) can be obtained during quiescence. We recently obtained detections of the black hole X-ray binary GX 339--4 in quiescence using the MeerKAT radio telescope and Swift X-ray Telescope instrument onboard the Neil Gehrels Swift Observatory, probing the lower end of the radio:X-ray correlation. We present the properties of accretion and of the connected generation of jets in the poorly studied low-accretion rate regime for this canonical black hole XRB system.
