Holography for N=2*on S4

We find the gravity dual of N = 2* super-Yang-Mills theory on S-4 and use holography to calculate the universal contribution to the corresponding S-4 free energy at large N and large 't Hooft coupling. Our result matches the expression previously computed using supersymmetric localization in the field theory. This match represents a non-trivial precision test of holography in a non-conformal, Euclidean signature setting.
