Minimal Theory of Bigravity: construction and cosmology
Antonio De Felice, François Larrouturou, Shinji Mukohyama +1
Following the path of minimalism in alternative theories of gravity, we construct the "Minimal Theory of Bigravity" (MTBG), a theory of two interacting spin-2 fields that propagate…
Minimally modified gravity with an auxiliary constraint: a Hamiltonian construction
Zhi-Bang Yao, Michele Oliosi, Xian Gao +1
Working directly with a general Hamiltonian for the spacetime metric with the decomposition and keeping only the spatial covariance, we investigate the possibility of reducin…
Minimally Modified Gravity fitting Planck data better than CDM
Katsuki Aoki, Antonio De Felice, Shinji Mukohyama +3
We study the phenomenology of a class of minimally modified gravity theories called theories, in which the usual general relativistic Hamiltonian constraint is rep…
Constant roll and primordial black holes
Hayato Motohashi, Shinji Mukohyama, Michele Oliosi
The constant-roll inflation with small positive value of the constant-roll parameter has been known to produce a slightly red-tilted cu…
On the absence of conformally flat slicings of the Kerr spacetime
Antonio de Felice, François Larrouturou, Shinji Mukohyama +1
This work investigates the possibility of achieving a conformally flat slicing of the Kerr spacetime. We consider a hypersurface of the form , where are t…
Phenomenology in type-I minimally modified gravity
Katsuki Aoki, Antonio De Felice, Chunshan Lin +2
We study cosmology in a class of minimally modified gravity (MMG) with two local gravitational degrees of freedom. We classify modified gravity theories into type-I and type-II: th…
