Observational tests of MOdified Gravity (MOG) and MOND with cluster Abell 1689 acceleration data 

محمد حسین ژولیده (دانشکده فیزیک دانشگاه صنعتتی شریف)

 Abstract: The galaxy cluster system Abell 1689 has been well studied and yields good lensing and X-ray gas data. Modified gravity (MOG) is applied to the cluster Abell 1689 and the acceleration data is well fitted without assuming dark matter. Newtonian dynamics and Modified Newtonian dynamics (MOND) are shown not to fit the acceleration data, while a dark matter model based on the Navarro-Frenk-White (NFW) mass profile is shown to fit the acceleration data for the radial range r>200kpc.
