Consider a spiral galaxy that is moving directly away from Earth with a speed V = 3. 2 4 0 \ times 1 0 ^ 5 at its center, as shown in Figure 2 5-4 0 . The galaxy is also rotating about its center, such that points in its spiral arms are moving with a speed v = 5. 7 5 0 \ times 1 0 ^ 5 m / s relative to the center.

Question: 7. Spiral Galaxy - M51. This image is of a spiral galaxy (M51) that resembles what our Milky Way might look like if viewed from outside the galaxy Note how the curved spiral arms develop around the more quickly rotating central cluster of stars. Looking at the spiral arms from this viewpoint, in what direction is this galaxy rotating? a.

Solved To find the luminous mass of a spiral galaxy, we must
To find the luminous mass of a spiral galaxy, we must be able to see the whole disk along with the bulge. Ideally, we would observe the galaxy from directly above the plane of the disk of the galaxy, as shown here for the spiral galaxy M101, the Pinwheel galaxy. Identify some of the sources that contribute to the luminosity of a spiral galaxy.

Solved Consider a spiral galaxy that is moving directly away - Chegg
The galaxy is also rotating about its center, so that points in its spiral arms are moving with a speed v = 6.650×105 m/s relative to the center. If light with a frequency of 8.213×10 14 Hz is emitted in both arms of the galaxy, what frequency is detected by astronomers observing the arm that is moving toward the Earth?
