A Consistency Relation in Cosmology
arXiv:astro-ph/0703347 · doi:10.1103/PhysRevD.75.101301
Abstract
We provide a consistency relation between cosmological observables in general relativity without relying on the equation of state of dark energy. The consistency relation should be satisfied if general relativity is the correct theory of gravity and dark energy clustering is negligible. As an extension, we also provide the DGP counterpart of the relation.
