Deep learning identifies voids in NGC 628 with low association to known star clusters, supporting an evolutionary sequence from molecular clouds via stellar feedback to detached voids.
Simulations of an NGC 300-like galaxy find exponential distributions of feedback-driven bubble lifetimes and sizes that increase with galactocentric radius, plus matching Hα predictions.
