Contribution

It provides a new class of exact solutions in topologically massive gravity, including supersymmetric black holes and flat space configurations.

Findings

Supersymmetric solutions asymptotic to extremal BTZ black holes.

Solutions include flat space-time in the absence of a cosmological constant.

Abstract

We obtain a general class of exact solutions to topologically massive gravity with or without a negative cosmological constant. In the first case, we show that the solution is supersymmetric and asymptotically approaches the extremal BTZ black hole solution, while in the latter case it goes to flat space-time.
