The Surprisingly Steep Mass Profile of Abell 1689, from a Lensing Analysis of Subaru Images

Tom Broadhurst, Masahiro Takada, Keiichi Umetsu +4

Subaru observations of A1689 (z=0.183) are used to derive an accurate, model-independent mass profile for the entire cluster, r<2 Mpc/h, by combining magnification bias and distort…
