Study of f(T) Mass Function of Nearby Galaxy Clusters: Determining σ8
Mohammad Shafi Khan · Journal of Pharmaceutical Research International · 2021
This paper presents a new analytical method to determine amplitude of density fluctuations of 152 nearby clusters (z ≤ 0.15). We investigate the rms linear fluctuation in the mass distribution on scales of 8h−1M pc i.e. σ8 , by using Press-Shechter mass function. The mass functio...
