Eddington-Born-Infeld gravity and the large scale structure of the Universe
Máximo Bañados, Pedro G. Ferreira, Constantinos Skordis
It has been argued that a Universe governed by Eddington-Born-Infeld gravity can be compatible with current cosmological constraints. The extra fields introduced in this theory can…
A note on bigravity and dark matter
Máximo Bañados, Andrés Gomberoff, Davi C. Rodrigues +1
We show that a class of bi-gravity theories contain solutions describing dark matter. A particular member of this class is also shown to be equivalent to the Eddington-Born-Infeld…
Eddington-Born-Infeld action and the dark side of general relativity
Maximo Banados
We review a recent proposal to describe dark matter and dark energy based on an Eddington-Born-Infeld action. The theory is successful in describing the evolution of the expansion…
Eddington-Born-Infeld action for dark energy and dark matter
Maximo Banados
We argue that Einstein gravity coupled to a Born-Infeld theory provides an attractive candidate to represent dark matter and dark energy. For cosmological models, the Born-Infeld f…
