WebIndeed, using Kepler’s third law and the velocities of its satellite galaxies, the Andromeda galaxy is estimated to have a mass closer to 1.4 × 10 12 M Sun. The mass of the Milky Way Galaxy is estimated to be 8.5 × 10 11 M Sun, and so our Milky Way is turning out to be somewhat smaller than Andromeda. WebDec 21, 2003 · Abstract. We examine the properties of the host galaxies of 22 623 narrow-line active galactic nuclei (AGN) with 0.02 < z < 0.3 selected from a complete sample of 122 808 galaxies from the Sloan Digital Sky Survey. We focus on the luminosity of the [O iii]λ5007 emission line as a tracer of the strength of activity in the nucleus.We study how …
