Fountain-driven gas accretion by the Milky Way

Fountain-driven gas accretion by the Milky Way

Accretion of fresh gas at a rate of ∼ 1M☉yr−1 is necessary in star-forming disc galaxies, such as the Milky Way, in order to sustain their star-formation rates. In this work we present the results of a new hydrodynamic simulation supporting the scenario in which the gas required for star formation i...
