Unified cosmic history in modified gravity: from F(R) theory to Lorentz non-invariant models
Unified cosmic history modified gravity
2010/12/24
Classical generalization of general relativity is considered as gravitational alternative for unified description of the early-time inflation with late-time cosmic acceleration. The structure and cosm...

Stellar Structure Tests of Modified Gravity
2010/12/27
Theories that attempt to explain cosmic acceleration by modifying gravity typically introduces a long-range scalar force that needs to be screened on small scales. One common screening mechanism is t...
Goldstone's Theorem and Hamiltonian of Multi-galileon Modified Gravity
Goldstone's Theorem Hamiltonian Multi-galileon Modified Gravity
2010/12/23
The galileon model was recently proposed to locally describe a class of modified gravity theories, including the braneworld DGP model. We discuss spontaneous symmetry breaking of the self-accelerating...

Cosmological consequences Modified Gravity
2010/12/20
As an alternative to the LCDM concordance model, Scalar-Tensor-Vector Modified Gravity (MOG) theory reproduces key cosmological observations without postulating the presence of an exotic dark matter c...

In the context of $f(R)$ gravity theories, the issue of finding static and spherically symmetric black hole solutions is addressed. Two approaches to study the existence of such solutions are consider...
A useful guide for gravitational wave observers to test modified gravity models
gravitational wave modified gravity models
2010/3/17
We present an extension of a previously suggested test of all modified theories of gravity that would reproduce MOND at low accelerations. In a class of models, called "dark matter emulators", gravita...
