New ${\cal N} = 1$ supersymmetric $AdS_5$ backgrounds in Type IIA supergravity

Understand

We present a family of N=1 supersymmetric backgrounds in type-IIA supergravity and their lifts to eleven-dimensional supergravity.

• These are of the form $AdS_5 \times X^5$ and are characterised by an $SU(2)$ structure.
• The internal space, $X^5$, is obtained from the known Sasaki-Einstein manifolds, $Y^{p,q}$, via an application of non-Abelian T-duality.
