Charged Einstein-\ae ther black holes in $n$-dimensional spacetime

Understand

In this work, we investigate the $n$-dimensional charged static black hole solutions in the Einstein-\ae ther theory.

• By taking the metric parameter $k$ to be $1,0$, and $-1$, we obtain the spherical, planar, and hyperbolic spacetimes respectively.
• Three choices of the cosmological constant, $\Lambda>0$, $\Lambda=0$ and $\Lambda<0$, are investigated, which correspond to asymptotically de Sitter, flat and anti-de Sitter spacetimes.
• The obtained results show the existence of the universal horizon in higher dimensional cases which may trap any particle with arbitrarily large velocity.
