Abstract

We establish a map between AdS3×_3 \timesS2^2 and AdS7_7 solutions to massive IIA supergravity that allows one to interpret the former as holographic duals to D2-D4 defects inside 6d (1,0) CFTs. This relation singles out in a particular manner the AdS3×_3\timesS2^2 solution constructed from AdS3×_3\timesS3×^3\times CY2_2 through non-Abelian T-duality, with respect to a freely acting SU(2). We find explicit global completions to this solution and provide well-defined (0,4) 2d dual CFTs associated to them. These completions consist of linear quivers with colour groups coming from D2 and D6 branes and flavour groups coming from D8 and D4 branes. Finally, we discuss the relation with flows interpolating between AdS3×_3\timesS2×^2\timesT4^4 geometries and AdS7_7 solutions found in the literature.
