Using Small Black Holes To Detect Big Black Holes

Quote

An international team of astrophysicists with participation of the University of Zurich proposes a novel method to detect pairs of the biggest black holes found at the centers of galaxies by analyzing gravitational waves generated by binaries of nearby small stellar black holes.

The origin of supermassive black holes found at the centers of galaxies, is still one of the biggest mysteries in astronomy. They may have always been massive and formed when the Universe was still very young. Alternatively, they may have grown over time by accreting matter and other black holes. When a supermassive black hole is about to eat another massive black hole, this will emit gravitational waves, which are ripples in spacetime that propagate through the Universe.
