Although it is not nearly so active or . Specifically, this . are thought to harbor supermassive black holes, NASA's conclusion is that dark matter might be "torn apart" by intense gravity, creating exotic particles that, in turn, collide with normal, luminous matter, accelerating it to extreme velocities. In addition to being absorbed by a material, X-rays can also interact with the atoms, giving rise to diffraction or scattering of the X-rays. Figure 1: A simulation showing the turbulent plasma around a black hole. It accounts for most of the radio emission from active galactic nuclei (AGNs) thought to be powered by supermassive black holes in galaxies and quasars, and it dominates the radio continuum emission from star-forming galaxies like our own at frequencies below 30 GHz. We consider a synchrotron radiation from a charged particle moving in a bound orbit around a weakly magnetized Schwarzschild black hole (a static black hole immersed into a constant uniform magnetic field) in its equatorial plane, perpendicular to the magnetic field.
