Scientific paper

We present a weak lensing analysis of the rare major merger cluster Abell 2465 at z=0.245. Using deep CFHT i-band imaging we reconstruct the mass distribution, resolving the structure in this double cluster. We find the lensing cluster mass estimates to be consistent with the spectroscopic virial mass estimates of the two cluster components with masses of approximately 4 x 10^{14} solar masses. We also compare our lensing reconstruction to the distribution of hot X-ray gas in the region. Optical properties of the cluster are described in Wegner (2011; arXiv:1101.1451).
