Contribution of Population III Stars to Merging Binary Black Holes

Understand

A large number of mergers of binary black holes (BHs) have been discovered by gravitational wave observations since the first detection of gravitational waves 2015.

• Binary BH mergers are the loudest events in the universe, however their origin(s) have been under debate.
• There have been many suggestions for merging binary BHs.
• Isolated binary stars are one of the most promising origins.
