Phenomenology in minimal theory of massive gravity
We investigate the minimal theory of massive gravity (MTMG) recently introduced. After reviewing the original construction based on its Hamiltonian in the vielbein formalism, we reformulate it inExpand
Integrated Sachs-Wolfe-galaxy cross-correlation bounds on the two branches of the minimal theory of massive gravity
The minimal theory of massive gravity (MTMG) has two branches of stable cosmological solutions: a self-accelerating branch, which, except for the mass of tensor modes has exactly the same behavior ofExpand
Graviton Mass Might Reduce Tension between Early and Late Time Cosmological Data.
TLDR
It is found that the ΛCDM model is less probable than the MTMG by 2 orders of magnitude, and with the help of the cross-correlation between the integrated Sachs-Wolfe effect and the large-scale structure, the data pin down the graviton mass squared around μ^{2}≈-(3×10^{-33}  eV)^{2}, which is consistent with the latest bound.

Dark sector interaction: a remedy of the tensions between CMB and LSS data
The well-known tensions on the cosmological parameters $$H_0$$H0 and $$\sigma _8$$σ8 within the $$\Lambda $$ΛCDM cosmology shown by the Planck-CMB and LSS data are possibly due to the systematics inExpand
Minimal theory of massive gravity
Abstract We propose a new theory of massive gravity with only two propagating degrees of freedom. While the homogeneous and isotropic background cosmology and the tensor linear perturbations aroundExpand
Signatures of a Graviton Mass in the Cosmic Microwave Background
There exist consistent low energy effective field theories describing gravity in the Higgs phase that allow the coexistence of massive gravitons and the conventional 1/r potential of gravity. In anExpand
New graviton mass bound from binary pulsars
In Einstein's general relativity, gravity is mediated by a massless metric field. The extension of general relativity to consistently include a mass for the graviton has profound implications forExpand

TLDR
Alternative and related models of massive gravity such as new massive gravity, Lorentz-violating massive gravity and non-local massive gravity are presented. Expand
Remedy of some cosmological tensions via effective phantom-like behavior of interacting vacuum energy
Since physics of the dark sector components of the Universe is not yet well-understood, the phenomenological studies of non-minimal interaction in the dark sector could possibly pave the way toExpand
Measurements of H0 in modified gravity theories: The role of lensed quasars in the late-time Universe
In this work, we obtain measurements of the Hubble constant in the context of modified gravity theories. We set up our theoretical framework by considering viable cosmological $f(R)$ and $f(T)$Expand
