摘要:

我们银河系中孤立的黑洞至今还没有被探测到。我们在这里提出了一个全面的研究孤立的恒星质量天体物理黑洞,吸积星际气体从分子云在本地区域和中央分子区的可探测性。我们采用了一个国家的最先进的模型的吸积物理数值模拟支持,并研究了可观测的来源在无线电和X射线波段的数量,作为各种参数的函数。我们讨论特别是天体物理的不确定性对我们的预测在银河系的中心区域的明亮的X射线源的数量的影响。最后,我们考虑在无线电领域的未来发展,并评估SKA的潜力,以检测人口的天体物理黑洞吸积气体在我们的银河系。

英文摘要:

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.
