Abstract

We present AdS black hole solutions in four-dimensional N=2 gauged supergravity with the universal hypermultiplet. Here the axion field in this multiplet is dualized to a two-form field. This system is derived from ten-dimensional massive type IIA theory compactified on nearly-Kahler manifold in the presence of geometric fluxes and RR-fluxes. In this work we focus on the simplest coset space G_2/SU(3). Imposing the covariantly constant condition on all scalar fields, we obtain AdS black hole solutions with vanishing electromagnetic charges and arbitrary mass parameter.
