What are the influences of quasars on the formation and evolution of galaxies?
Understand the Problem
The question pertains to the influence of quasars on the formation and evolution of galaxies, discussing their role in emitting high-energy radiation and impacting star formation and galaxy growth.
Answer
Quasars expel gas, inhibit star formation, and affect galaxy evolution.
Quasars influence galaxy formation and evolution by expelling gas, inhibiting star formation, and contributing to the 'quasar feedback' mechanism. They play a role in transitioning galaxies to gas-poor, non-star-forming states.

Quasars influence galaxy formation and evolution by expelling gas, inhibiting star formation, and contributing to the 'quasar feedback' mechanism. They play a role in transitioning galaxies to gas-poor, non-star-forming states.
More Information
Quasars, powered by supermassive black holes, were more common in the early universe and have significant effects on their host galaxies. They heat and expel gas, prevent new stars from forming, and mark stages in galaxy evolution.
Tips
A common mistake is overlooking the significant impact of the radiation and energy output from quasars on their host galaxies.
