Quasars Suppress Star Formation by Ejecting Molecular Gas
Gas on the Run – ALMA Spots the Shadow of a Molecular Outflow From a Quasar When the Universe Was Less Than One Billion Years Old

Researchers from Hokkaido University, the University of Tsukuba, Waseda University, and other institutions have confirmed the discovery of molecular gas outflows from a quasar when the Universe was less than one billion years old. This molecular gas, vital for star formation, is being ejected into intergalactic space by the quasar, effectively suppressing star formation in its host galaxy. The study was conducted using the ALMA telescope in Chile, which has the sensitivity to detect molecular outflows in the early Universe. These findings offer strong evidence that quasars influence galaxy evolution by regulating star formation through molecular gas ejection. This discovery enhances understanding of the early Universe’s evolution and the role quasars play in shaping galaxies.
