Black hole luminosity

WebSo a black hole like the one whose mass you found in the previous activity (with a temperature of 6000 K) would emit light with a spectrum identical to that of the Sun; recall that a Planck emitter (sometimes referred to as a blackbody) has a spectrum that depends only on its temperature. WebThe first direct image of a supermassive black hole, located at the galactic core of Messier 87. It shows radio-wave emission from a heated accretion ring orbiting the object at a mean separation of 350 AU, or ten times larger than the orbit of Neptune around the Sun. The dark center is the event horizon and its shadow. The image was released in 2024 by the …
