论文摘要

最近的观察结果表明,许多星系中心存在超质量黑洞。还预测了球状簇中中间质量黑洞(IMBH)的存在。我们专注于重力镜头,作为探索这些实体的新方法。众所周知,根据中央巨大物体的存在或不存在,诸如球形簇之类的自我散热系统的质量分布大大变化。在考虑了属于银河系的球状簇的可能质量分布之后,我们估计对IMBH引起的重力镜头分离角的影响将是Milliarcsec的。

Recent observations suggest the presence of supermassive black holes at the centers of many galaxies. The existence of intermediate-mass black holes (IMBHs) in globular clusters has also been predicted. We focus on gravitational lensing as a new way to explore these entities. It is known that the mass distribution of a self-gravitating system such as a globular cluster changes greatly depending on the presence or absence of a central massive object. After considering possible mass distributions for a globular cluster belonging to the Milky Way galaxy, we estimate that the effect on the separation angle of gravitational lensing due to an IMBH would be of milliarcsecond order.
