We study supersymmetric , solutions in seven-dimensional maximal gauged supergravity with and gauge groups. These gauged supergravities are consistent truncations of eleven-dimensional supergravity and type IIB theory on and , respectively. Apart from recovering the previously known solutions in SO(5) gauge group, we find novel classes of , and solutions in non-compact SO(3, 2) gauge group together with a class of solutions in SO(4, 1) gauge group. In SO(5) gauge group, we extensively study holographic RG flow solutions interpolating from the SO(5) supersymmetric vacuum to the fixed points and singular geometries in the form of curved domain walls with slices. In many cases, the singularities are physically acceptable and can be interpreted as non-conformal phases of -dimensional SCFTs obtained from twisted compactifications of SCFT in six dimensions. In SO(3, 2) and SO(4, 1) gauge groups, we give a large number of RG flows between the new fixed points and curved domain walls while, in gauge group, RG flows interpolating between asymptotically locally flat domain walls and curved domain walls are given.
