  • MMTO aids in new discovery

    Astronomers at the University of Arizona and the University of Wyoming have discovered a pair of quasars at high redshift using, in part, spectra obtained at the MMTO. The quasars are surprisingly bright and close together - an unusual find that may eventually lead to a better understanding of the early growth of the most massive black holes in the universe. Whether the discovery was a chance find or whether there are many more pairs of quasars at similar distances will have to wait for a more comprehensive search. In the meantime, you can read more details here.
