Rotating black holes in three-dimensional Ho\v{r}ava gravity

Understand

We study black holes in the infrared sector of three-dimensional Ho\v{r}ava gravity.

• It is shown that black hole solutions with anti-de Sitter asymptotics are admissible only in the sector of the theory in which the scalar degree of freedom propagates infinitely fast.
• We derive the most general class of stationary, circularly symmetric, asymptotically anti-de Sitter black hole solutions.
• We also show that the theory admits black hole solutions with de Sitter and flat asymptotics, unlike three-dimensional general relativity.
