Abstract
We construct a simple model of the star-formation- (and resultant supernova) driven mass and energy flows through the inner∼200pc (in diameter) of the Galaxy. Our modelling is constrained, in particular, by the non-thermal radio continuum and γ-ray signals detected from the region. The region’s star-formation activity drives an outflow of plasma, cosmic rays, and entrained, cooler gas. The plasma outflow from the Galactic Centre (GC) reaches a height of a few kpc and is compellingly related to the recently-discovered Fermi Bubbles by a number of pieces of evidence. In general, our investigations explicitly reveal the GC’s important role in the Milky Ways wider stellar ecology.
