The emission lines in the spectrum of TON 618 have been found to be unusually wide, [7] indicating that the gas is travelling very fast; the full width half maxima of TON 618 has been the largest of the 29 quasars, with hints of 10,500 km/s speeds of infalling material by a direct measure of the H β spectral line, indication of a very strong ...
Ton 618 (this quasar has possibly the biggest black hole ever found, estimated at 66 billion solar masses) [1] 3C 371; 4C +37.11 (this radio galaxy is believed to have binary supermassive black holes) [2] AP Lib; S5 0014+81 (said to be a compact hyperluminous quasar, estimated at 40 billion solar masses) [3]
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.

The most famous Lyman-alpha blobs were discovered in 2000 by Steidel et al. [1] Matsuda et al., using the Subaru Telescope of the National Astronomical Observatory of Japan extended the search for LABs [2] and found over 30 new LABs in the original field of Steidel et al., [1] although they were all smaller than the originals. These LABs form a ...
