Constraining Black Hole Populations in Globular Clusters using Microlensing: Application to Omega Centauri

John Zaris, Doğa Veske, Johan Samsing +3

We estimate the rate of gravitational microlensing events of cluster stars due to black holes (BHs) in the globular cluster NGC 5139 ($\omega Cen$). Theory and observations both indicate…
