Astronomers See Disks Surrounding Black Holes, Strengthened Evidence For Current Explanation Of Quasars

For the first time, researchers have found a way to view the accretion disks surrounding black holes and verify that their true electromagnetic spectra match what astronomers have long predicted they would be. A black hole and its bright accretion disk have been thought to form a quasar, the powerful light source at the center of some distant galaxies. Using a polarizing filter, astronomers isolated the light emitted by the accretion disk from that produced by other matter in the vicinity of the black hole.
