Explore the properties of dual active galactic nuclei (AGNs) that evolve into gravitational wave sources in this 50-minute conference talk by Tamara Bogdanovic from Georgia Tech. Delve into the journey from kiloparsec scales to merger, examining the dynamics and characteristics of these fascinating binary systems. Gain insights into the evolution of circumbinary gas, its influence on embedded binaries, and the observational signatures that provide valuable information. Learn about the latest numerical techniques used to model these complex systems and understand the similarities between massive black hole binaries and stellar binaries. Discover the cutting-edge research presented at the "Building Bridges: Towards a Unified Picture of Stellar and Black Hole Binary Accretion and Evolution" conference hosted by the Kavli Institute for Theoretical Physics, bridging the gap between two distinct astrophysical communities.
