It is a very useful astrophysical tool with some astounding successes. Einstein rings, giant luminious arcs, galactic microlensing event, and weak gravitational lensing. Other aspects of it were determined in interest to multiply-imaged quasar. The concept became observational science after the discovery of the first doubly imaged quasar in 1979. background sources, and possibility of determining Hubble’s constant with lensing. ![]() For example, use of lens as gravitational telescope on very imperceptible and distant objects, probability of multiple or ring like images of. Various aspects and attributes of gravitational lens effect were probed theoretically by some of the brightest minds in the following decades. In this project, we will study the basic plasma physics, application of virial theorem to constrain the mass distribution of the clusters then compare them with the mass distribution constrained from the radiation received from them (bremsstrahlung emissivity), gravitational lensing by cluster of galaxies and discuss about the majority of missing mass which holds these clusters and its constituent galaxies together.Įinstein’s famous General Relativity concept gave rise to Gravitational lensing, which was confirmed in 1919. In the upcoming future, the investigation of clusters will empower us to handle significant mysteries like the bizarre nature of Dark Matter (DM). We are finding out much about how these structures form, specifically how clusters as nodes in the vast cosmic web develop and accumulate matter, and about the physical processes inside these. ![]() The improved comprehension of clusters’ morphology and kinematics are likewise significant for the fruitful utilization of clusters as tests to study the vast large-scale structure. The X-ray and optical observational research of the last decade has brought broad progress in the understanding of galaxy clusters. In spite of the fact that superclusters are largest in size and mass, they overcome the gravitational attraction and expand with the flow expansion of the Universe. ![]() Galaxy clusters are massive, virial, self-gravitating systems in the Universe.
