Halton Arp tried unsuccessfully to prove that these objects could be connected by gaseous bridges, and they are distinguished from BL Lac objects because their continuum spectra show unusual emission lines, which were first ex- plained by Maarten Schmidt. These objects reached their peak population in the universe about ten billion years ago, and the first to be discovered was 3C 273, located in the constellation Virgo. These objects operate under the same mechanism as radio galaxies, with their name derived from the fact they are very strong radio sources, though they are now thought to surround the central supermassive black holes of large galaxies. Producing ten to one hundred times more energy than the entire Milky Way in an area the size of our solar system, name these extremely distant objects, the most luminous objects in the universe.
