Abstract
We generate new AdS4 solutions of D = 11 supergravity starting
from AdS4 × X7 solutions where X7 has U(1)3 isometry.
We consider examples where X7 is weak G2, Sasaki-Einstein or
tri-Sasakian, corresponding to d = 3 SCFTs with 
= 1,2 or 3
supersymmetry, respectively, and where the deformed solutions preserve
= 1,2 or 1 supersymmetry, respectively. For the special cases
when X7 is M(3,2), Q(1,1,1) or N(1,1)I we identify the
exactly marginal deformation in the dual field theory. We also show
that the volume of supersymmetric 5-cycles of N(1,1)I agrees with
the conformal dimension predicted by the baryons of the dual field
theory.
