Dark matter from the Weyl projection of bulk matter in five-dimensional gravity

Abstract

We propose that the dark matter inferred in galaxies arises from the Weyl projection of bulk matter in five-dimensional gravity onto a brane. We derive the projected Einstein equations, the Abel-inversion kernel, and a near-cold equation of state, and show that a two-parameter model reproduces the cored dark-matter population of the SPARC database while passing BBN/CMB constraints. This record contains the preprint (PDF) and the full supplementary material (codes, data, and figure scripts) needed to reproduce every number and figure in the paper; a reproduction-mapping table is provided in the supplement README.
