What lurks in the centers of globular clusters? Intermediate-mass black holes, stellar mass black holes, compact stars, or nothing special?

Abstract Globular star clusters are the largest self-gravitating systems that are collisional (short 2-body relaxation times). Their inner dynamics are complicated by three- and four-body encounters, mass loss from stellar evolution, and astrophysical phenomena that lead to ejection. I will present recent analyses of the stellar kinematics in nearby globular clusters using proper motions from Gaia and HST. This allows us to map the inner mass profile and test for the existence and extent of a possible dark inner component, which could be an intermediate-mass black hole or populations of stellar-mass black holes, neutron stars, or white dwarfs. This helps answer the question: are globular clusters prime locations for the emission of gravitational waves in the Universe?
