Cold quasar

Last updated

A cold quasar is a rare population of luminous unobscured quasars associated with starburst galaxies with a high rate of star formation of about 1000 solar masses per year. These quasars have a significant amount of cold gas at the center of the galaxy. [1] Theses rare types of quasars are not well explained by simplistic models of quasar evolution and fueling. [2]

There are 64 galaxies that are described to host a cold quasar. [1] [2]

Discovery

The discovery of cold quasars was formally announced in 2019 by Professor Allison Kirkpatrick at the 234th meeting of the American Astronomical Society in St. Louis. [3]
