Web3 de dez. de 2024 · X-rays originate from places where matter is under extreme conditions – violent collisions, enormous explosions, 10-million-degree temperatures, fast rotations, and strong magnetic fields. X-rays hold the key to understanding these phenomena, but because Earth’s atmosphere blocks them from reaching us they can only be observed … Web14 de jun. de 2013 · The paper, recently published in Astrophysical Journal, states that as gas spirals toward a black hole through a formation called an accretion disk, it heats up to roughly 10 million degrees Celsius. The temperature in the main body of the disk is roughly 2,000 times hotter than the sun and emits low-energy, or "soft," X-rays.

WebIf a black hole passes a gas cloud, the gases in the cloud will be forced to accelerate. This will emit radiation (X-rays, mostly), which we can measure. An improvement on this is the Zel'dovitch-Novikov proposal, which looks at black holes in a binary system with a star. Part of the solar winds from the star will be sucked in to the black hole. Web11 de dez. de 2024 · Supermassive black holes at the center of galaxies can also accrete nearby gas and dust, which make them active ("active galactic nuclei", or AGN).
