They used improved search methods to dig deeper into publicly available data from LIGO\u2019s and Virgo\u2019s first and second observation runs. Apart from confirming the ten known binary black hole mergers and one binary neutron star merger, they also identify four promising black hole merger candidates, which were missed by initial LIGO\/Virgo analyses. These results demonstrate the value of searches in public LIGO\/Virgo data by research groups independent of the LIGO\/Virgo collaborations.
