We provide the first supersymmetric embedding of an integrable
λ-deformation to type-II supergravity. Specifically, that of the near
horizon of the NS1-NS5 brane intersection, geometrically corresponding to
AdS3​×S3×T4. We show that the deformed background preserves
1/4 of the maximal supersymmetry. In the Penrose limit we show that it
preserves no-more than one half of the maximal supersymmetry.Comment: 24 pages, 1 figur
