WebThe most spectacular accretion disks found in nature are those of active galactic nuclei and of quasars, which are thought to be massive black holes at the center of galaxies. As matter enters the accretion disc, it … WebDec 17, 2014 · In an accretion disk, viscosity causes each ring of gas to spiral inward toward the hole with a radial speed $ u^r \ll\text{(orbital velocity)} = (M/r)^{1/2}$. If this were the only effect of viscosity, the warping of the disk would consist of a differential precession.
WebOur results can also provide more realistic initial conditions for simulations of black hole accretion at the event horizon scale. AB - We present high-resolution, three-dimensional hydrodynamic simulations of the fueling of supermassive black holes in elliptical galaxies from a turbulent medium on galactic scales, taking M87* as a typical case. Web8 minutes ago · The image captured by the Event Horizons Telescope (EHT) in 2024 revealed a blurry, red-orange fiery, doughnut-shaped object. The updated picture using AI has been published in the Astrophysical Journal Letters which shows the same shape of the black hole, albeit with a much sharper resolution. Meaning, the ring around the black …
