How Can Stars and Active Black Holes Reshape Their Host Galaxy?

When does energetic feedback compress, heat, expel, or redistribute gas?

Follow energy from young stars and an active nucleus into galactic gas, then compare heating, outflow, retention, and compression as measurable outcomes rather than one universal shutdown switch.

An original reconstruction of a tilted galaxy with a bright active nucleus, amber bipolar outflow, cool gas lanes, and star-forming regions along the disk. — Vastward-generated artistic reconstruction of stellar and active-nucleus feedback. It is not a telescope photograph; real Hubble evidence appears below.
