Black holes, compact objects and solar system tests in non-relativistic general covariant theory of gravity
Jared Greenwald, V. H. Satheeshkumar, Anzhong Wang
We study spherically symmetric static spacetimes generally filled with an anisotropic fluid in the nonrelativistic general covariant theory of gravity. In particular, we find that…
Stability, ghost, and strong coupling in nonrelativistic general covariant theory of gravity with
Yongqing Huang, Anzhong Wang
In this paper, we investigate three important issues: stability, ghost and strong coupling, in the Horava-Melby-Thompson setup of the Horava-Lifshitz theory with , genera…
Cosmology in nonrelativistic general covariant theory of gravity
Anzhong Wang, Yumei Wu
Horava and Melby-Thompson recently proposed a new version of the Horava-Lifshitz theory of gravity, in which the spin-0 graviton is eliminated by introducing a Newtonian pre-potent…
Stability of spin-0 graviton and strong coupling in Horava-Lifshitz theory of gravity
Anzhong Wang, Qiang Wu
In this paper, we consider two different issues, stability and strong coupling, raised lately in the newly-proposed Horava-Lifshitz (HL) theory of quantum gravity with projectabili…
Vector and tensor perturbations in Horava-Lifshitz cosmology
Anzhong Wang
We study cosmological vector and tensor perturbations in Horava-Lifshitz gravity, adopting the most general Sotiriou-Visser-Weinfurtner generalization without the detailed balance…
Semitransparent pistons
P. Morales, K. Kirsten
We consider semitransparent pistons in the presence of extra dimensions. It is shown that the piston is always attracted to the closest wall irrespective of details of the geometry…
