Explain your answer. Can a spiral turn into an elliptical? How?arrow_forward
- If we see a double image of a quasar produced by a gravitational lens and can obtain a spectrum of the galaxy that is acting as the gravitational lens, we can then put limits on the distance to the quasar. Explain how.arrow_forwardDoes an elliptical galaxy rotate like a spiral galaxy? Explain.arrow_forwardWhat is the most useful standard bulb method for determining distances to galaxies?arrow_forward
- Using the information from Example 28.1, how much fainter an object will you have to be able to measure in order to include the same kinds of galaxies in your second survey? Remember that the brightness of an object varies as the inverse square of the distance.arrow_forwardWhat does it mean if one elliptical galaxy has broader spectrum lines than another elliptical galaxy?arrow_forwardWhat is the most useful probe of the early evolution of the universe: a giant elliptical galaxy or an irregular galaxy such as the Large Magellanic Cloud? Why?arrow_forward
- Astronomers have been making maps by observing a slice of the universe and seeing where the galaxies lie within that slice. If the universe is isotropic and homogeneous, why do they need more than one slice? Suppose they now want to make each slice extend farther into the universe. What do they need to do?arrow_forwardSuppose we could measure the distance to a galaxy using one of the distance techniques listed in Table 26.2 and it turns out to be 200 million light-years. The galaxy’s redshift tells us its recessional velocity is 5000 km/s. What is the Hubble constant?arrow_forwardDescribe the evolution of an elliptical galaxy. How does the evolution of a spiral galaxy differ from that of an elliptical?arrow_forward
