TL;DR
This paper reviews the critical role of feedback mechanisms, such as supernovae and black holes, in addressing key challenges in galaxy formation theory, including star formation efficiency and galactic star formation rates.
Contribution
It provides a comprehensive review of how feedback processes help resolve major issues in galaxy formation models.
Findings
Feedback mechanisms are essential for regulating star formation.
Supernovae and black holes significantly influence galaxy evolution.
Feedback improves agreement between models and observations.
Abstract
I review the outstanding problems in galaxy formation theory, and the role of feedback in resolving them. I address the efficiency of star formation, the galactic star formation rate, and the roles of supernovae and supermassive black holes.
