Binary Black Hole Mergers: Physical Mechanisms

A binary black hole merger proceeds through inspiral, merger, and ringdown. Black-hole mergers measure the population of stellar remnants, test relativity, constrain binary formation channels, and reveal black holes that may be electromagnetically invisible.

A binary black hole merger proceeds through inspiral, merger, and ringdown.

supported

Gravitational radiation removes energy and angular momentum, raising orbital frequency as separation decreases.

supported

Detected chirp waveforms match general-relativistic templates across inspiral, merger, and ringdown.
