Weak lensing analysis of RXC J2248.7-4431

Understand

We present a weak lensing analysis of the cluster of galaxies RXC J2248.7-4431, a massive system at z=0.3475 with prominent strong lensing features covered by the HST/CLASH survey (Postman et al.

• 2012).
• Based on UBVRIZ imaging from the WFI camera at the MPG/ESO-2.2m telescope, we measure photometric redshifts and shapes of background galaxies.
• The cluster is detected as a mass peak at 5sigma significance.
