Description
In this talk, I will discuss the construction of two supersymmetric solutions of type-II supergravity based on the λ-deformed σ-models for SL(2,R) and SU(2). In the absence of deformation, they describe near-horizon limits of NS1 and NS5 brane intersections and both are 1/2-supersymmetric. When the deformation is turned on, supersymmetry breaks by half and both backgrounds preserve 8 supercharges.
