Massive (Quantum) Gravity in Three Dimensions

I review work done in collaboration with E. Bersghoeff and P. Townsend on a novel version of massive gravity in three dimensions. The action is quadratic in curvatures, and it propagates unitarily a massive graviton with two polarisation states of helicity +2/-2. The model appears to be (super-)renormalizable and admits black hole and cosmological solutions. Unitarity and stability of its cosmological vacua are examined as well as supersymmetric extensions and the relation to `chiral gravity'.
