TL;DR

This paper investigates how super-light brane world modes alter the Newtonian potential at large distances, affecting galaxy clustering and virial theorem, with implications for cosmic structure formation.

Contribution

It introduces a model of modified Newtonian potential due to brane world modes and analyzes its impact on galaxy clustering and virial equilibrium.

Findings

Modified potential affects galaxy clustering patterns

Virial theorem is altered by the new potential

Potential implications for large-scale structure formation

Abstract

In this paper, we study the effects of super-light brane world perturbative modes on structure formation in our universe. As these modes modify the large distance behavior of Newtonian potential, they effect the clustering of a system of galaxies. So, we explicitly calculate the clustering of galaxies interacting through such a modified Newtonian potential. We use a suitable approximation for analyzing this system of galaxies, and discuss the validity of such approximations. We observe that such corrections also modify the virial theorem for such a system of galaxies.
