If you only eat one bagel today, this is the bagel.
Summary
Recent research suggests that most stellar-mass black hole mergers occur in triple systems, where a close inner binary black hole pair is orbited by a more distant third companion. With hundreds of black hole merger signals now detected by LIGO, Virgo, and KAGRA gravitational wave observatories, scientists are investigating the environments and mechanisms that lead to these cosmic collisions, finding evidence that triple systems may be the primary site for such mergers.
