Recent discoveries regarding the existence of the large–scale structures in the universe, especially on the scales where the Cosmological Principle is expected to be accurate, pose a challenge to the Standard Model of Cosmology (ΛCDM model). These structures extend beyond 200 – 300 Mpc (Haines, Clowes, and Campusano, 2000; Gott III et al., 2005; Clowes et al., 2013; Horváth, Hakkila, and Bagoly, 2014, Lopez et al., 2021) provide strong evidence of anisotropy against the ΛCDM model as there should not be clumping of objects within that scale. The work of Migkas et al. (2020, 2021) also observed a similar anisotropic behavior of galaxy clusters towards a particular direction in the night sky. However, there is still no clear explanation for how to explain these observations. From this, the researcher aims to describe these anisotropies and their nature by viewing them through a theoretical lens.
