A cold quasar is a rare population of luminous unobscured quasars associated with starburst galaxies with an high rate of star formation of about 1000 solar masses per year. Theses 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
editThe 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]
