The mass structure of a spiral galaxy may be determined by measurement of its rates of rotation.
Spiral galaxy called milky way was explained by Edwin Hubble 1936. They are two types ordinary and barred. Spiral galaxy has smooth disk and halo component without spiral arm and their mass structure of a spiral galaxy is determined by measurement of oits rate of rotation. While mass structure of of elleptical galaxies are determined and analaysed by motion of stars within them..
Hope it helps!!!

Part of a foreground spiral galaxy (S) overlaps part of an elliptical galaxy (E). The background elliptical has a surface brightness of IE= IS= 21 mag arcsec^-2. What is the combined observed surface brightness I obs in a patch where they overlap? Use Vega as a reference star since its mV= mB= 0.

Consider a spiral galaxy that is moving directly away from Earth with a speed V=3.24*10^5 at its center. The galaxy is also rotating about its center such that points in the spiral arms are moving with a soeed V=5.750*10^5m/s relative to the center. If light with a frequency of 7.308*10^14Hz is emitted in both arms of the galaxy, what frequency is detected by astronomers observing the arm that is moving (a) toward and (b) away from Earth? Please break down...

Stars in elliptical galaxies move like the bulge or halo stars in spiral galaxies. a. Why can’t the rotation curve method to determine mass be used for elliptical galaxies? b. Masses of elliptical galaxies are often derived from their velocity dispersions. This part illustrates how a velocity dispersion can be determined: The intrinsic line-width of a K giant star might be 0.5 Å at a central wavelength λ0 = 5000 Å. Suppose an elliptical galaxy is observed which has a...

Globular clusters are spherical clusters of stars that orbit a galaxy, some of the older ones in the Milky Way are 13 Gyr old. At what distance would these globular clusters cease to spiral into the galactic nucleus due to the effects of dynamical friction if it has a mass of 6×106M⊙ and an orbital speed of 230 km/s?

Galaxies contain both stars and dark matter. The mass M of a galaxy that is located within a certain star's orbit is given by where v is the velocity of the star, r is the distance from the galaxy's center to the star, and G is Newton's gravitational constant, 6.673 x 10- N m/kg Stars near the edge of a particular galaxy have velocities of 259 km/s. The radius of the galaxy is 53 kpc. How much mass is in...
