Insights from the Two-Dimensional Binary Black Hole Mass Distribution

Explore groundbreaking insights into the two-dimensional binary black hole mass distribution in this 43-minute conference talk that examines how gravitational wave detections are transforming our understanding of stellar mass black hole populations. Discover how multiple observational methods—including Gaia's detection of dormant black holes in detached binaries, microlensing studies of isolated black holes, and time domain surveys tracking black hole formation transients—are revealing new populations that complement traditional X-ray and radio survey findings. Learn about the complex lifecycle of stellar black holes, from their massive star progenitors through core collapse and associated transients, to their existence as dormant or accreting objects, and their potential fate as gravitational wave sources during mergers. Gain understanding of how these diverse detection methods are providing a comprehensive view of black hole demographics and evolution, while identifying key observational and theoretical strategies needed to address fundamental questions about stellar black hole lifecycles in modern astrophysics.
