DISCREPANT MASS ESTIMATES IN THE CLUSTER OF GALAXIES ABELL 1689
We present a new mass estimate of a well studied gravitational lensing cluster, Abell 1689, from deep Chandra observations with a total exposure of 200 ks. Within r = 200 h[superscript -1] kpc, the X-ray mass estimate is systematically lower than that of lensing by 30%-50%. At r>200 h[superscript...
