Assigned ID: 958 ----- Attempting Submission 1 (Sat Feb 26 02:48:00 GMT 2011) ----- We propose to test the Cold Dark Matter paradigm by measuring the central dark matter ellipticity and density profiles for a sample of 18 massive, dynamically relaxed galaxy clusters. We will detect, or place strict limits on, the presence of isothermal dark matter cores using simultaneous statistical modeling of strong & weak gravitational lensing and X-ray data. These measurements will place strong and robust constraints on self interacting dark matter models. Such constraints, when combined with dark matter annihilation cross section constraints, have the potential to rule out a class of dark matter models commonly used to explain anomalies observed across a number of prominent, current dark matter experiments.
