报告题目：The Search for Black Holes in Globular Clusters

　　报 告 人：Irwin, James A. (University of Alabama)

　　摘    要：The existence of both stellar- and intermediate-mass black holes within globular clusters has been the subject of intense debate for decades. The rich globular cluster populations of nearby elliptical galaxies provide much more fertile hunting grounds over the meager globular cluster population of the Milky Way to search for accreting black holes emitting near their Eddington limit. Extreme X-ray variability of >1e39 ergs/s sources provide the best means of identifying such black holes. I will present the current evidence for black hole existing within globular clusters, and discuss the possibility that intermediate-mass (100-10,000 dolar mass) black holes reside at the centers of globular clusters much like supermassive black holes reside at the centers of galaxies.
