Computer Simulations Visualized the Disk of the Milky Way Galaxy for Three Cases

Caption

Computer simulations visualized the disk of the Milky Way Galaxy for three cases: no impact with a dwarf galaxy, impact with a Sgr dwarf galaxy of lower mass, and impact with a Sgr dwarf galaxy of higher mass. Our Galaxy is shown both edge-on and face-on in the inset panels, and the sun's location is marked as a yellow dot, and the present location of the Sagittarius dwarf's remnant core is marked as a pink dot, as shown after more than two billion years of isolated evolution. Shown in the background is a global rendering of the "light Sgr" tidal debris and the Milky Way disk.
