The life cycle of the Central Molecular Zone - I. Inflow, star formation, and winds

Armillotta, Lucia; Krumholz, Mark; Di Teodoro, Enrico Maria; McClure-Griffiths, Naomi


We present a study of the gas cycle and star formation history in the central 500 pc of the Milky Way, known as Central Molecular Zone (CMZ). Through hydrodynamical simulations of the inner 4.5 kpc of our Galaxy, we follow the gas cycle in a completely self-consistent way, starting from gas radial inflow due to the Galactic bar, the channelling of this gas into a dense, star-forming ring/stream at ≈200–300 pc from the Galactic centre, and the launching of galactic outflows powered by...[Show more]
