NuSTAR and XMM-Newton view of the interaction between the galaxy cluster A3395 and A3395/A3391 intercluster filament

According to large scale structure (LSS) formation scenarios, Galaxy Clusters (GCs) are thought to have formed hierarchically via mergers of smaller scale structures. Thermodynamical properties of the X-ray emitting intracluster medium are sensitive probes of these dynamical activities. In this talk, I will present the joint NuSTAR and XMM-Newton analysis of the GC A3395 (z = 0.0498) at the site where the cluster and the filament connecting A3395 and A3391 meet in projection. Although XMM-Newton detects a hot-spot in this location, which may point to accreted structures and/or internal dynamics, we find that NuSTAR does not agree with this result (possibly) due to its insensitivity to spatially varying foreground absorption that XMM-Newton suffers from. The interaction of cosmic web filaments and GCs, as we explore in our joint analysis of A3395, can help improve our understanding of the formation and growth of LSS.
