Explore the revolutionary discoveries transforming our understanding of stellar mass black holes through this 48-minute conference talk by Vicky Kalogera from Northwestern University. Examine how gravitational wave detections, Gaia observations of dormant black holes in detached binaries, microlensing studies of isolated black holes, and time domain surveys searching for transients are unveiling new black hole populations that complement previously known accreting systems from X-ray and radio surveys. Analyze the complete lifecycle of stellar black holes, from the complicated evolution of their massive star progenitors through core collapse and associated transients, to their afterlives as dormant or accreting objects, and their potential finale as gravitational wave sources during mergers. Discover how these emerging datasets are compelling astronomers to reassess theoretical models and develop new observational strategies to address fundamental questions about black hole formation, evolution, and detection across multiple astronomical domains.
