Have you seen this missing black hole?
Supermassive black holes, which lurk at the centers of most galaxies including the Milky Way, can be spotted by their gravitational effects and the brilliant radiation of ill-fated stars and gas that they consume.
But a distant galaxy called A2261-BCG, located 2.6 billion light years away, lacks clear signs of a black hole, even though it should contain a real whopper with a mass between three and 100 billion Suns.
The mystery of the missing black hole inside A2261-BCG persists even after a dedicated search effort with the powerful Chandra X-ray Observatory, according to a forthcoming study. In addition to looking for the object at the center of the galaxy, scientists investigated the possibility that it was forcefully ejected from the galactic core, which would make it a never-before-seen “recoiling black hole.”
