MMT Data used in Discovery of Unprecedented Supermassive Black Hole

Leave a Comment

Astronomers from Peking University in China and the University of Arizona have discovered the most luminous quasar known at a redshift of greater than 6. The ultra-luminous quasar has a black hole that clocks in with a mass of about 12 billion times the mass of the Sun. This incredible object was discovered and characterized in part with the Red Channel Spectrograph at the MMT. Its existence is a challenge for current theories of black hole formation and growth and may support claims that supermassive black holes grew much more quickly in the early universe in comparison to their host galaxies.
