Explore the revolutionary discoveries of dormant black holes through Gaia Data Release 3 in this 13-minute conference talk. Learn how gravitational wave detections are transforming our understanding of stellar mass black hole populations, while Gaia unveils previously unknown dormant black holes in detached binary systems with stellar companions. Discover how microlensing techniques probe isolated black holes that would otherwise remain unobservable, and examine how time domain surveys search for transients that mark either the birth of black holes or their interactions with stellar companions. Understand how these diverse detection methods are revealing new black hole populations that complement the accreting black holes long known from X-ray and radio surveys. Examine 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 either dormant or accreting objects, and their potential finale as gravitational wave sources during mergers. Gain insights into the latest observational findings and theoretical strategies being developed to address urgent questions about stellar black hole evolution, presented as part of a comprehensive conference bringing together experts to review recent discoveries in this rapidly advancing field.
