The Impact of Feedback on Disk Galaxy Scaling Relations

Understand

We use a disk galaxy evolution model to investigate the impact of mass outflows (a.k.a.

• feedback) on disk galaxy scaling relations.
• Our model follows the accretion, cooling, star formation and ejection of baryonic mass inside growing dark matter haloes, with cosmologically motivated specific angular momentum distributions.
• Models without feedback produce disks that are too small and rotate too fast.
