Unveiling Supermassive Black Holes and Their Binaries

Supermassive black holes have emerged over the last decade as a cornerstone of astronomy, astrophysics, and public engagement with science, though their foundational importance was established as early as the 1960s. This book serves as an introduction to the evolving frontiers of modern astronomy and cosmology, with supermassive black holes and their binaries as the unifying theme. It examines the theoretical and observational investigations that have revealed the pivotal role of such binaries in shaping cosmic evolution. Woven throughout is the social and historical landscape that made these discoveries possible, along with the compelling human stories of the researchers behind them. The book further offers a window into recent advances in gravitational wave astronomy and explores the far-reaching implications of detecting mergers between supermassive black holes.
