Dark matter in ghost-free bigravity theory: From a galaxy scale to the universe
Katsuki Aoki, Kei-ichi Maeda
We study the origin of dark matter based on the ghost-free bigravity theory with twin matter fluids. The present cosmic acceleration can be explained by the existence of graviton m…

Cosmology in ghost-free bigravity theory with twin matter fluids: The origin of "dark matter"
Katsuki Aoki, Kei-ichi Maeda
We study dynamics of Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime based on the ghost-free bigravity theory. Assuming the coupling parameters guaranteeing the existence of d…
