Quasi-Local Mass in a Binary Black Hole Merger

Explore a detailed General Relativity seminar presentation examining the complex challenge of defining mass in finite spatial regions within classical general relativity, focusing on the Wang-Yau mass definition from 2009. Learn how this mathematical framework compares extrinsic geometries by embedding closed 2-surfaces into Minkowski space, and discover its practical applications in understanding black hole dynamics. Follow along as the speaker demonstrates the computational methods for Wang-Yau mass, extends its definition to quasi-local horizons in black holes, and analyzes its behavior during binary black hole mergers. Gain insights into cutting-edge research from the Max Planck Institute that bridges theoretical concepts with practical applications in black hole physics.
