AdS5 black strings in the stu model of FI-gauged N=2 supergravity

We analytically construct asymptotically AdS(5) black string solutions starting from the four-dimensional domain wall black hole of [1]. It is shown that its uplift gives a black string in d = 5 minimal gauged supergravity, with momentum along the string. Applying instead the residual symmetries of N = 2, d = 4 Fayet-Iliopoulos-gauged super-gravity discovered in [2] to the domain wall seed leads, after uplifting, to a dyonic black string that interpolates between AdS(5) and AdS(3) x H-2 at the horizon. A Kaluza-Klein reduction of the latter along an angular Killing direction phi followed by a duality transformation yields, after going back to five dimensions, a black string with both momentum along the string and rotation along phi. This is the first instance of using solution-generating techniques in gauged supergravity to add rotation to a given seed. These solutions all have constant scalar fields. As was shown in [3], the construction of supersymmetric static magnetic black strings in the FI-gauged stu model amounts to solving the SO(2, 1) spinning top equations, which descend from an inhomogeneous version of the Nahm equations. We are able to solve these in a particular case, which leads to a generalization of the Maldacena-Nunez solution.
