Abstract
Galaxy clusters are one of the largest structures that are probes to study astrophysics and cosmology. The correct estimation of cluster masses can help us constrain cosmological parameters. 12% of its mass comes from the intracluster medium(ICM) and hence, understanding ICM would help in accurately measuring the mass. This mass can be further compared to the mass obtained through weak gravitational lensing to understand dark matter distribution. In my thesis, the aim is to extract the 3D thermodynamic properties of the ICM. The backward-fitting and forward-fitting models are used for this purpose. This thesis gives a detailed view of the theory involved in both models. It presents a comparative analysis of the results from both methods and checks its reliability.
