An X-ray quiet black hole born with a negligible kick in a massive binary within the Large Magellanic Cloud

Tomer Shenar, Hugues Sana, Laurent Mahy +35

Stellar-mass black holes are the final remnants of stars born with more than 15 solar masses. Billions are expected to reside in the Local Group, yet only few are known, mostly det…
