Evolution of massive fields around a black hole in Horava gravity
Evolution of massive fields black hole Horava gravity
2010/12/20
We study the time evolution of massive scalar field in the spacetime geometry of Kehagias-
Sfetsos(KS) black hole in deformed Hoˇrava-Lifshitz(HL) gravity by numerical analysis. We find
that the sig...
Unified cosmic history in modified gravity: from F(R) theory to Lorentz non-invariant models
2010/12/20
Classical generalization of general relativity is considered as gravitational alternative for unified description of the early-time inflation with late-time cosmic acceleration. The structur and cosmo...
Generic Gravity Tests with the Double Pulsar
double pulsar gravity tests preferred-frame effects
2010/3/18
Presently the double pulsar allows for the measurement of six post-Keplerian parameters. In addition, its double-line nature gives access to the projected semi-major axes of both orbits. We use this w...
We introduce a new approach for investigating the weak field limit of vacuum field equations in f(R) gravity and we find the weak field limit of f(R) = R +{mu}^4/R gravity. Furthermore, we study the s...
