Abstract

We study the parameter space of magnetically charged AdS2×WCP[n,n+]1_2\times\mathbb{WCP}^{1}_{[n_-,n_+]} solutions in 4d U(1)4(1)^4 gauged STU supergravity. We show that both \emph{twist} and \emph{anti-twist} solutions are realised and give constraints for their existence in terms of the magnetic charges of the solution. We provide infinite families of both classes of solution in terms of their magnetic charges and weights of the orbifold. As a byproduct of our analysis we obtain a closed form expression for the free-energy of the 4-charge magnetic solution in terms of the magnetic charges and weights n±n_{\pm}. We also show that the AdS2_2 solution is the near-horizon of an asymptotically AdS4_4 black hole which can be found in the literature.
