The discovery had been made possible thanks to a phenomenon known as gravitational lensing — the first time a black hole has been spotted in such a way. by Wagamaga The technique used to detect the black hole in this case is to use a model to predict what the image would look like with and without the black hole. The model that fits the data best is consistent with a black hole of the size quoted. Permalink Parent 2
