Many recent studies have sought to pinpoint 'dust-reddened' ones of these through LoBALs, or broad absorption lines.
Many recent studies have sought to pinpoint 'dust-reddened' ones of these through LoBALs, or broad absorption lines. Neutral hydrogen clouds create a characteristic suppression in their spectra in the Gunn-Peterson Effect. They were first discovered by Marten Schmidt, and Einstein's theory of gravitational lensing was first confirmed by one of them. Their spectral energy is believed to arise from large amounts of matter falling into regions of extreme gravity. Characterized by very high redshifts and believed to be powered by supermassive black holes, for 10 points, identify these super-powerful active galactic nuclei.
