$\Lambda$CDM $\cup$ MOND

TL;DR

This paper shows that the Renormalised Brane World model can explain galaxy rotation curves without dark matter by producing deviations from Newtonian gravity at large distances, aligning with Milgrom's MOND hypothesis.

Contribution

It demonstrates that RBW model deviations mimic MOND effects in spherically symmetric systems, providing an alternative explanation for galaxy rotation curves.

Findings

RBW deviations occur at large distances in spherical systems.

These deviations explain flat galaxy rotation curves.

The results align RBW with MOND without dark matter.

Abstract

It has been demonstrated that the difference between the Renormalised Brane World (RBW) model and the Lambda Cold Dark Matter ($\Lambda$CDM) model occurs only at sufficiently distant times. In this paper, it is shown that for spherically symmetric situations an analog deviation between the RBW model and Newton's theory occurs at large distances. More precisely, this deviation of the RBW model is nothing other than the explanation of Milgrom's hypothesis and follows from itself. Therefore, the results of this paper explains flat rotation curves of galaxies without dark matter.
