All major arms in these galaxies show spiral arm\nwidth increasing with distance from the galactic center, similar to the trend\nseen in the Milky Way. However, in the outer-most parts of the galaxies, where\nmassive star formation declines, some arms reverse this trend and narrow. We\n...
When the Milky Way and a s-galaxy are respectively on the two side of an oblong empty hole or inside a huge s-empty hole, an observer on the earth will observe the s-galaxy to be brighter than its real brightness. The luminous arc structure of galaxies which is near the central part...
