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.

What if the first stars were only 1-50 times as massive as the Sun? Would they still be able to enrich the intergalactic medium and trigger the birth of the next generation of stars?

In this series of papers, the authors apply new analysis techniques to data from several galaxy redshift surveys to uncover acoustic waves from the early universe and refine measurements of cosmological parameters.
