What mechanism, observed using the Chandra X-ray Observatory, can shut down star formation besides gas exhaustion?

Answer

Heating or blowing away cool gas via energetic gas from an active galactic nucleus (AGN)

Chandra observations show that hot, energetic gas, often originating from an AGN, can heat the necessary cooler gas or effectively blow it away, quenching star birth through feedback.
