Explore the dynamics of merging black hole binaries in this 49-minute lecture by Manuela Campanelli from Rochester Institute of Technology. Delve into accretion dynamics, outflows, and computational challenges in multi-messenger astrophysics. Discover the latest research on supermassive binaries, simulation techniques, and the potential for light emission from binary systems. Learn about the evolution of black hole mergers, resolving physics in simulations, and the impact of black hole spin. Gain insights into future work in this field and participate in a discussion on the treatment of assimilation in astrophysical models.
