AI总结:

针对候选超大质量双黑洞SDSS J1430+2303,研究即将并合的超大质量黑洞双星引力波源的探测需求,提出扩展的Taiji pathfinder-plus方案有望探测近距源,以助力探索黑洞性质与引力本质。

摘要:

近期报道的超大质量双黑洞候选体SDSS J1430+2303,促使我们研究一类即将并合的超大质量黑洞双星作为潜在引力波源的情况,研究表明其并合末期辐射的引力波处于空间探测器的探测频段内。我们对探测这类引力波源所需的探测灵敏度开展了通用分析,并结合两种典型设计构型的空间天线展开了全面讨论。若源的距离足够近,通过Taiji pathfinder-plus(太极探路者+,是对规划中的Taiji pathfinder(太极探路者)的扩展方案,仅需在初始两颗卫星的基础上新增一颗卫星)就有可能实现探测。对这类源的引力波探测,将助力我们探究超大质量黑洞的性质与引力的本质。

英文摘要:

A supermassive binary black-hole candidate SDSS J1430+2303 reported recently motivates us to investigate an imminent binary of supermassive black holes as potential gravitational wave source, the radiated gravitational waves at the end of the merger are shown to be in the band of space-borne detectors. We provide a general analysis on the required detecting sensitivity needed for probing such type gravitational wave sources and make a full discussion by considering two typically designed configurations of space-borne antennas. If a source is so close, it is possible to be detected with Taiji pathfinder-plus which is proposed to be an extension for the planned Taiji pathfinder by just adding an additional satellite to the initial two satellites. The gravitational wave detection on such kind of source enables us to explore the properties of supermassive black holes and the nature of gravity.
