This is a catalogue of dormant (non-accreting) black holes detected within binaries and in isolation.
It is complementary to the catalgoue of black holes in X-ray transients (
Blackcat
) and the catalogue of black hole masses
detected in gravitational wave events (
LIGO/VIRGO mass plot
).
It was created during The Renaissance of Stellar Black-Hole Detections in The Local Group meeting at the Lorentz Centre, June 26-30 2023.
The background image is an artist’s impression of VFTS 243, a massive binary in the Large Magellanic Cloud which hosts a dormant black hole. Credit: ESO/L. Calçada.
