Cosmological galaxy evolution with superbubble feedback – I. Realistic galaxies with moderate feedback
Abstract
We present the first cosmological galaxy evolved using the modern smoothed particle hydrodynamics (SPH) code gasoline2 with superbubble feedback. We show that superbubble-driven galactic outflows powered by Type II supernovae alone can produce L* galaxies with flat rotation curves with circular velocities ∼ 200 km s− 1, low bulge-to-disc ratios, and stellar mass fractions that match observed values from high redshift to the present. These …
