论文摘要
到目前为止,我们银河系中孤立的黑洞已经避免了检测。我们在这里介绍了一项关于分离的恒星天体物理黑洞的可检测性的全面研究,该黑洞是从局部区域和中央分子区域中分子云中积聚星形气体的。我们采用了由数值模拟支持的积物物理学的最先进模型,并研究无线电和X射线频带中可观察到的源数量,这是多种参数的函数。我们特别讨论了天体不确定性对我们预测银河系中心区域明亮X射线源数量的影响。我们最终考虑了无线电领域的未来发展,并评估了SKA检测我们银河系中积聚气体的天体物理黑洞人群的潜力。
Isolated black holes in our Galaxy have eluded detection so far. We present here a comprehensive study on the detectability of isolated stellar-mass astrophysical black holes that accrete interstellar gas from molecular clouds in both the local region and the Central Molecular Zone. We adopt a state-of-the-art model for the accretion physics backed up by numerical simulations, and study the number of observable sources in both the radio and X-ray band, as a function of a variety of parameters. We discuss in particular the impact of the astrophysical uncertainties on our prediction for the number of bright X-ray sources in the central region of the Galaxy. We finally consider future developments in the radio domain, and assess the potential of SKA to detect a population of astrophysical black holes accreting gas in our Galaxy.
