Constraints on bimetric gravity from Big Bang nucleosynthesis
Marcus Högås, Edvard Mörtsell
Bimetric gravity is a ghost-free and observationally viable extension of general relativity, exhibiting both a massless and a massive graviton. The observed abundances of light ele…

Observational constraints on bimetric gravity
Marcus Högås, Edvard Mörtsell
Ghost-free bimetric gravity is a theory of two interacting spin-2 fields, one massless and one massive, in addition to the standard matter particles and fields, thereby generalizin…

Analytical constraints on bimetric gravity
Marcus Högås, Edvard Mörtsell
Ghost-free bimetric gravity is an extension of general relativity, featuring a massive spin-2 field coupled to gravity. We parameterize the theory with a set of observables having…
