Apex Andromeda · GWOSC population
Confident GWTC events with at least one mass-qualified black-hole component. Detection confidence and component classification remain separate claims.
Both lower mass bounds above 3 M☉ classify a binary-black-hole event. A secondary interval below 3 M☉ classifies a black-hole–neutron-star event; intervals crossing the boundary remain candidates. Binary-neutron-star-only events are excluded.
