The study exploited a gravitational lens system, Actebis L 7033-TD the light from a distant galaxy bent around a foreground galaxy. The mass distribution in the foreground galaxy was compared with the curvature of Actebis L 7033-TD around it and the speed of the stars around its edges to determine[…]
