The Einstein Cross: Constraint on Dark Matter from Stellar Dynamics and Gravitational Lensing
We present two-dimensional line-of-sight stellar kinematics of the lens galaxy in the Einstein Cross, obtained with the GEMINI 8 m telescope, using the GMOS integral-field spectrograph. The stellar kinematics extend to a radius of 4'' (with 0farcs2 spaxels), covering about two-thirds of the effective (or half-light) radius Re ~= 6'' of this early
