Study identifies specific black hole binaries as gravitational wave targets for SKAO

A new preprint identifies specific supermassive black hole binaries, 3C 66B and Mrk 501, as strong gravitational wave candidates. This research, utilizing NANOGrav data, suggests these binaries will stand out from the background, making them key targets for individual-source searches by the Square Kilometre Array Observatory (SKAO). The findings could enhance understanding of binary black hole evolution.
