What is the primary difference between a galaxy that is 'starved' versus one that is 'artificially quenched'?

Answer

Starved implies fuel depletion, while artificial implies external forces prevented gas accumulation.

A starved galaxy has used up its fuel supply through prolonged intense star formation, whereas an artificially quenched galaxy is inhibited by external factors preventing cold gas accumulation.
