Elusive medium-sized black holes may form in dense ‘birth nests’

Researchers have discovered that elusive intermediate-mass black holes can form in dense star clusters containing tens of thousands to millions of tightly packed stars, called “globular clusters.” An intermediate-mass black hole has a mass between 100 and 10,000 suns. They are heavier than solar-mass black holes, which have masses between 10 and 100 solar masses,… Read More »
