Webthe galaxy, including dark matter. We can go further in cases of spherical symmetry. Spherical symmetry means that the gravitational acceleration at a distance Rfrom the centre of the galaxy is simply GM(R)=R2, where M(R) is the mass interior to the radius R. In this case, v2 circ R = GM(R) R2 and therefore, vcirc = r GM(R) R: (5.1) WebOct 1, 2024 · These galaxies have most of their mass in a spherical-shaped denser region called a bulge, while the rest of their mass exists in the arms of stars and dust spiraling on relatively the same...
