When Quasars Collide STJC
Summary
This episode explores the first detection of a pair of supermassive black holes in a tight binary orbit within the Seyfert galaxy Markarian 533. The hosts discuss how astronomers used Very Long Baseline Interferometry to distinguish two distinct jets, confirming the presence of two separate black holes. The discussion covers the implications for understanding black hole growth and the "final parsec problem," while also addressing why gravitational waves from such massive systems are undetectable by LIGO.
