Black hole mass and angular momentum in topologically massive gravity

Understand

We extend the Abbott-Deser-Tekin approach to the computation of the Killing charge for a solution of topologically massive gravity (TMG) linearized around an arbitrary background.

• This is then applied to evaluate the mass and angular momentum of black hole solutions of TMG with non-constant curvature asymptotics.
• The resulting values, together with the appropriate black hole entropy, fit nicely into the first law of black hole thermodynamics.
