- Hubble's galaxy classification diagram (the "tuning fork") O suggests the existence of black holes O shows how galaxies evolve from one form to another O relates galaxies according to their shapes, but not according to any evolutionary status O explains active galactic nuclei EGO38. Many RR Lyrae stars are found in open clusters in the plane of the galaxy. True FalseThe Milky Way grew through merging with many smaller galaxies. What are the observational signatures of this process? O The motion of old stars in the bulge and halo of our galaxy are randomly orientated, meaning they were formed from collisions of small, accreted, galaxies all on different paths. O The ordered motion of the bulge / halo stars means that they came from many objects. The random motions of stars in the disk means it was formed from collisions of small, accreted, galaxies. O The motion of young stars in the disk are all in the same direction, meaning they came in as seperate objects.
- Distance Based on the graph above, the expansion rate of galaxies near us is than galaxies that are farther away. O faster slower O the same rate VelocitySuppose you have obtained spectra of several galaxies and have measured the observed wavelength of the H-Alpha line (rest wavelength = 656.3 nm) to be Galaxy 1: 658.1 nm. Galaxy 2: 667.1 nm. Galaxy 3: 677.6 nm. Calculate the radial velocity of each of these galaxies.
