Constraining Cosmological Parameters Using the Splashback Radius of Galaxy Clusters

Cosmological parameters such as Ω M and σ 8 can be measured indirectly using various methods, including galaxy cluster abundance and cosmic shear. These measurements constrain the composite parameter S 8 , leading to degeneracy between Ω M and σ 8 . However, some structural properties of galaxy clus...
