Unveiling the internal structure of the Hercules supercluster

We have investigated the structure of Hercules supercluster (SCL160) based on data originally extracted from Sloan Digital Sky Survey SDSS-DR7. traced mass distribution in field through numerical density-weighted by $r^\prime$-luminosity galaxies and classified them their spatial position redshift. This has allowed us not only to address kinematics as a whole, but also internal kinematic each cluster, which was no further explored before. confirmed that is composed galaxy clusters A2147, A2151, A2152. A2151 consists five subclusters, A2147 two A2152 at least two. They form heart supercluster. found other gravitationally bond clusters, increasing, therefore, known members estimated total $2.1\pm0.2 \times 10^{15}$ M$_\odot$ for To determine dynamical masses this work, we resorted $M_{200}-\sigma$ scaling relation caustic technique. Comparing both methods with simulated bimodal merging caustic, well $\sigma$-based masses, are biased merger age, showing boost just after pericentric passage. line principle method affirms it depending cluster state.
