Ch. 18 Study Questions 1. What do you call an object that has a starlike image,

Ch. 18 Study Questions
1. What do you call an object that has a starlike image, a highly redshifted spectrum, and is sometimes an intense radio emitter?
2. What causes the extreme redshifts of quasars?
3. The power output of a typical quasar is how many times greater than the Milky Way’s power output?
4. What is the size of a typical quasar?
5. Which quasar is smaller: one that fluctuates rapidly in brightness, or one that fluctuates slowly in brightness?
6. What does a “peculiar” galaxy look like?
7. If an electron in a magnetic field is emitting synchrotron radiation, how is the electron moving? That is, what is the shape of its path as it flies along?
8. Where would you look to find a supermassive black hole?
9. Describe the energy generating system in a quasar.
10. What is the name of the phenomenon when a foreground galaxy produces multiple images of a distant quasar?
