Detection of IMBHs from microlensing in globular clusters

Globular clusters have been long predicted to host intermediate-mass black holes (IMBHs) in their centres. The growing evidence that some/all Galactic globular clusters (GCs) could harbour middle range (10² - 10⁴M_⊙) black holes, just as galaxies do, stimulates the searches and the development of new methods for proving their existence. Here we propose another method of detection - the microlensing of the cluster stars by the central BH.
