Enhancing and extending NuSTAR’s capabilities with the characterization of scattered light background: implications for observations of galaxy clusters

Abstract: Galaxy clusters are the largest gravitationally bound structures in the universe. According to large scale structure formation scenarios, they are hierarchically formed by mergers of smaller scale structures, which are the most energetic (10^65 ergs/s) processes in the universe that drive shocks and turbulence into the intracluster medium (ICM). Thermodynamical properties of the X-ray emitting ICM are sensitive probes of these dynamic activities. Although we have advanced X-ray satellites to observe these phenomena, there are caveats in interpreting their data; the most challenging one being the characterization of the background. In this talk, I will present our techniques and approaches to obtain the true data of clusters of galaxies from the X-ray mission NuSTAR, and share the process of how we deduce the real emission on a working example of the cluster Abell 3395.
