Astronomers discover a unique quasi-stellar object–dusty star-forming galaxy system

Astronomers from the Steward Observatory in Arizona and elsewhere report the discovery of a structure consisting of a quasi-stellar object (QSO) and a dusty star-forming galaxy (DSFG), linked by a bridge of ionized carbon. The finding of this unique system was detailed in a paper published November 11 on the pre-print server arXiv.
