Dispersion relation and surface gravity of universal horizons
Chikun Ding, Changqing Liu
In Einstein-aether theory, violating Lorentz invariance permits some super-luminal communications, and the universal horizon can trap excitations traveling at arbitrarily high velo…

Effects of Homogeneous Plasma on Strong Gravitational Lensing of Kerr Black Holes
Changqing Liu, Chikun Ding, Jiliang Jing
Considering a Kerr black hole surrounded by the homogenous unmagnetised plasma medium, we study the strong gravitational lensing on the equatorial plane of the Kerr black hole. We…

Three-dimensional charged Einstein-aether black holes and Smarr formula
Chikun Ding, Changqing Liu, Anzhong Wang +1
We investigate the three-dimensional behavior of gravity coupled to a dynamical unit timelike vector: the aether, and present two new classes of exact charged solutions. When c_{13…
