Abstract

We present a large class of new backgrounds that are solutions of type IIB supergravity with a warped AdS5{}_5 factor, non-trivial axion-dilaton, BB-field and three-form Ramond-Ramond flux but yet have no five-form flux. We obtain these solutions and many of their variations by judiciously applying non-Abelian and Abelian T-dualities, as well as coordinate shifts to AdS5×X5{}_5\times X_5 IIB supergravity solutions with X5=S5,T1,1,Yp,qX_5=S^5, T^{1,1}, Y^{p,q}. We address a number of issues pertaining to charge quantization in the context of non-Abelian T-duality. We comment on some properties of the expected dual super conformal field theories by studying their CFT central charge holographically. We also use the structure of the supergravity Page charges, central charges and some probe branes to infer aspects of the dual super conformal field theories.
