发射线作为寻找超大质量黑洞双星和黑洞的工具

Emission Lines as a Tool in Search for Supermassive Black Hole Binaries and Recoiling Black Holes

Tamara Bogdanovic, Michael Eracleous, Steinn Sigurdsson

摘要:

探测并合前双星的电磁(EM)对应物对于我们理解这些系统的演化以及相关的吸积物理具有非常重要的意义。此外,从合并的超大质量黑洞双星(SBHB)中观测到的电磁波和引力波信号的组合将提供对红移和光度距离的独立测量,从而允许高精度的宇宙学测量。然而,这些物体的统计学上的重要样本尚未获得,并且通过观测发现它们已被证明是一项艰巨的任务。在这里,我们将讨论现有的观测证据,以及如何在合并之前和之后的SBHB的观测签名的理论理解的进一步进展,可以帮助在未来的搜索。

英文摘要:

Detection of electromagnetic (EM) counterparts of pre-coalescence binaries has very important implications for our understanding of the evolution of these systems as well as the associated accretion physics. In addition, a combination of EM and gravitational wave signatures observed from coalescing supermassive black hole binaries (SBHBs) would provide independent measurements of redshift and luminosity distance, thus allowing for high precision cosmological measurements. However, a statistically significant sample of these objects is yet to be attained and finding them observationally has proven to be a difficult task. Here we discuss existing observational evidence and how further advancements in the theoretical understanding of observational signatures of SBHBs before and after the coalescence can help in future searches.
