Finding Structure Among Black Holes

New research has explored the populations of black holes involved in catastrophic, gravitational-wave-emitting collisions — and an interesting pattern has emerged.

Science with a Single Merger Event

Future gravitational-wave observatories could enable us to use a single binary neutron star merger to measure the universe’s rate of expansion.
