We investigate higher spin theories of gravity in three dimensions based on the gauge group SL(N,R)*SL(N,R). In these theories the usual diffeomorphism symmetry is enhanced to include higher spin gauge transformations under which…

We construct a new class of charged, rotating hairy black holes in a consistent truncation of $\mathcal{N} = 8$ supergravity, which retains one charged scalar field and a U$(1)$ gauge field. These hairy solutions can be uplifted to…
We consider N=8 gauged supergravity in D=4 and D=5. We show one can weaken the boundary conditions on the metric and on all scalars with $m^2 <-{(D-1)^2 \over 4}+1$, while preserving the asymptotic anti-de Sitter (AdS) symmetries. Each…
