Massive and Passive Galaxies due to Early Quasar Driven Outflows

Massive and Passive Galaxies due to Early Quasar Driven Outflows

In the nearby Universe, massive galaxies contain very little interstellar gas and old stellar populations. But theoretical models predict that such galaxies should have much younger stellar populations. In order to solve this discrepancy models invoke quasar outflows in the early Universe. Such outflows would expel the gas from a galaxy and quench star formation. Presented here are the results from the first massive quasar outflow observer at z ~ 6.4189.
