"Milky Way Galaxy.rar" is a common file name for a collection of research rather than a single scientific paper, with key studies covering 3D maps using OGLE data and relativistic dynamics. Notable academic resources include the Ruffini-Argüelles-Rueda (RAR) model and reviews detailing galactic mass. For a detailed 3D map based on OGLE, see the research found at ResearchGate .
