WebbAlthough most galaxies with no supermassive black holes are very small, dwarf galaxies, one discovery remains mysterious: The supergiant elliptical cD galaxy A2261-BCG has not been found to contain an active supermassive black hole of at least 10 10 M ☉, despite the galaxy being one of the largest galaxies known; over six times the size and one thousand … 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.

They can spit out as much as 90% of the energy from the matter that falls into them, and 2) once they reach a certain size, black holes are too large to form accretion disks, so matter tends to orbit around them rather than funnel into them.
