Gemini Probes Milky Way’s Dark Matter Halo

Many properties of the Milky Way halo, like its mass, are not well known, and not all the mass is even ordinary matter. Direct measurements of the proper motions of objects in the halo can disentangle properties that are otherwise undistinguished, and these observations of dwarf galaxies and globular clusters also provide insight into the […]

Solar Panel Installation Begins at Gemini North
