Scientists discover rare quasar triplet 9 billion light years away
Brian Sin, Mar 12th 2013
A team of international researchers, lead by Emanuele Farina from the University of Insubria in Como, Italy, have discovered a rare, quasar triplet about 9 billion light years away from Earth. The quasar triplet has been named QQQ J1519+0627 and is only the second triplet to ever be found. The researchers believe that the galaxies that these quasars are a part of may be merging together in order to form one, enormous galaxy ....
Michele Fumagalli, an astrophysicist at the Observatories of the Carnegie Institution in Pasadena, said, “Honing our observational and modeling skills and finding this rare stellar phenomenon will help us understand how cosmic structures assemble in our universe and the basic processes by which massive galaxies form.” The system is difficult to observe, however, due to their distance. It’s difficult for the scientists to distinguish the quasar triplets from the other different astronomical bodies nearby ...
