Vaidya Solution in General Covariant Hořava-Lifshitz Gravity with the Minimum Coupling and without Projectability: Infrared Limit
O. Goldoni, M. F. A. da Silva, R. Chan +1
In this paper, we have studied nonstationary radiative spherically symmetric spacetime, in general covariant theory ( extension) of {the} Hořava-Lifshitz gravity with the min…
A Lorentz Gauge Theory of Gravity
Ahmad Borzou
We present a Lorentz gauge theory of gravity in which the metric is not dynamical. Spherically symmetric weak field solutions are studied. We show that this solution contains the S…
New look at black holes: Existence of universal horizons
Kai Lin, O. Goldoni, M. F. da Silva +1
In this paper, we study the existence of universal horizons in a given static spacetime, and find that the test khronon field can be solved explicitly when its velocity becomes inf…
Universal horizons and black holes in gravitational theories with broken Lorentz symmetry
Kai Lin, Elcio Abdalla, Rong-Gen Cai +1
In this paper, we first show that the definition of the universal horizons studied recently in the khrononmetric theory of gravity can be straightforwardly generalized to other the…
