The original Event Horizon Telescope image of the supermassive black hole at the heart of galaxy M87 (left) was the first to capture the shadow of a black hole’s event horizon. Researchers have reconstructed that image using machine learning to sharpen details (right). Webb4 okt. 2013 · To determine size of a black hole first you need to determine its Schwarzschild Radius using this formula Rs= (2MG)/ (c^2). To determine its photo-sphere use the formula 3Rs/2 and extends from the surface of its Rs, to determine its accretion disk (PNR for matter) it is 5.5Rs and measured from the surface of its Rs threshold.

Webb5 jan. 2016 · A black hole behaves as though its horizon has a temperature and that temperature is inversely proportional to the hole's mass: T = (6 x 10^-8)M. Here M is in units of solar mass (2 x 1033 grams). Temperature is in degrees Kelvin. WebbSize comparison of the event horizons of the black holes of TON 618 and Phoenix A. The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc .
