Galaxy kinematics in the X-ray luminous galaxy cluster Abell 1835

Robert Schmidt, University of Heidelberg

We present a combined analysis of X-ray mass models and galaxy velocity data for the galaxy cluster Abell 1835. From Chandra X-ray data the dark matter and total mass profiles in this cluster have been measured. Combining the X-ray mass profile with radial velocity data for more than 600 cluster members obtained by Czoske (2004) allows us to study the velocity anisotropy of the cluster galaxies. We show how the results compare with the predictions from cold dark matter simulations.
