AdS2 geometries and non-Abelian T-duality in non-compact spaces

We obtain an AdS(2) solution to Type IIA supergravity with 4 Poincare supersymmetries, via non-Abelian T-duality with respect to a freely acting SL(2,R) isometry group, operating on the AdS(3)xS(3)xCY(2) solution to Type IIB. That is, non-Abelian T-duality on AdS(3). The dual background obtained fits in the class of AdS(2)xS(3)xCY(2) solutions to massive Type IIA constructed in [1]. We propose and study a quiver quantum mechanics dual to this solution that we interpret as describing the backreaction of the baryon vertex of a D4-D8 brane intersection.
