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.

A grand design spiral galaxy has which of the following attributes? many spiral segments but no real spiral arms. two main spiral arms. very few bright, blue stars in its spiral arms. many spiral arms

3. Galaxy NGC 4414 in (Figure 3). 4. Galaxy NGC 1300 in (Figure 4). 5. Galaxy M87 in (Figure 5). NGC4594 M101 is obviously a barred spiral. It is an SBb or SBc galaxy, given how tightly its spiral arms are wrapped. M87 NGC 1300 NGC 4414 is a face-on spiral galaxy. It does not have a bar, its bulge is not very large, and its spiral arms are not ...

A Spiral Galaxy of type Sb has a maximum rotational velocity of 233 km/s at a radius of 25 kpc. Estimate the Mass-to-Light ratio in the B-band for this galaxy. That is, calculate the ratio of (M/Lb) where M is the mass and L is the luminosity in the B-band.

What is the major difference between an elliptical galaxy and a spiral galaxy? (A) A spiral galaxy contains mostly younger stars. (B) A spiral galaxy has a spherical halo. (C) An elliptical galaxy lacks a disk component. (D) Elliptical galaxies are not as big as spiral galaxies. E) There are no dwarf spiral galaxies, but there are dwarf ...

a) (2 pts) In a spiral galaxy far far away, a star system 2 4, 0 0 0 light years away from the center of that galaxy is orbiting around the center at a speed of about 3 0 0 k m s. Assuming the orbit is perfectly circular, what is the total mass in that galaxy enclosed within that star system's orbit (in solar masses)?

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.

A Spiral Galaxy has a maximum rotational velocity of 267 km/s at a radius of 25 kpc. Estimate the Mass of this galaxy within this Radius? Please give your answer in solar masses to a 3% accuracy. If your answer is 6.5e11 Solar Masses, you will have to enter: 650000000000.

To discern the different parts of a spiral galaxy, one method is to analyze the orbits of stars and their populations, otherwise known as metallicity. Step 1 In order to discern the different parts of a spiral galaxy, scientists primarily rely on the analysi...

Part II: Motions of Stars One way to estimate the amount of mass in a spiral galaxy is by looking at how much light the galaxy emits. Where there is more light emitted by different regions of a galaxy, they often find that more light is emitted from the center of the galaxy and less light is emitted from the outer regions. 7) Based on the ...
