We propose observation of SPT-CL J0356-5337 comma a bullet-like cluster candidate at zvirgul1 comma in order to identify the multiple centers of X-Ray emission from the ICM. The configuration of this cluster shows two massive components at the cluster core comma separated by 172kpc. One component is dominated by the BCG comma whereas the other hosts a group of eight galaxies within 60kpc. Merger events happen on short timescales relative to the lifetime of the cluster therefore only a handful of clusters have been observed yet comma mainly at lower z. Combined with HST data we can constrain both the hot gas and the dark matter potential using strong and weak lensing. Studying such rare high redshift cluster brings more insight into our distant universe in preparation for future X-ray observatories.
