Does the Presence of an AGN in a Galaxy Affect

question 19

Multiple Choice

Does the presence of an AGN in a galaxy affect star formation rates in the galaxy?

• A) No. Star formation rates in galaxies with AGN are similar to those in galaxies of the same type and size without AGN.
• B) Yes. The presence of an AGN and its jets sends out shock waves that cause star formation to occur at an elevated rate throughout the disk of the galaxy.
• C) Yes. It has a negative effect. The presence of the AGN heats the gas and dust throughout the galaxy, thus making it less likely to collapse to form stars.
• D) This question has different answers for different host galaxies. An AGN in a spiral galaxy causes increased star formation rates, but an AGN in an elliptical galaxy has no effect on the (very low) star formation rate.
