Galaxy #2 is far less luminous than our Milky Way. How many galaxies of this luminosity would you need to match the light output of the Milky Way?Notice how the light profile (the radial plot of counts) can be divided into an inner region and an outer region (with a change of slope between them). The names for the two galaxy components that these two regions represent are theConsider the total B-V color measured across all of Galaxy #4. What value do you find if you reduce the size of the ellipse to contain just the bright golden nucleus of the galaxy? What types of galaxies have this B-V color overall?Note the dark band running along the disk of Galaxy #6, and the bright splotch slightly offset from the center as defined by the rest of the galaxy. These factors will lead to a higher asymmetry index.
