Non-K\"ahler Expanding Ricci Solitons II

We produce new non-K"ahler, non-Einstein, complete expanding gradient Ricci solitons with conical asymptotics and underlying manifold of the form $\R^2 \times M_2 \times \cdots \times M_r$,where$r \geq 2$and$M_i$ are arbitrary closed Einstein spaces with positive scalar curvature. We also find numerical evidence for complete expanding solitons on the vector bundles whose sphere bundles are the twistor or $\mathrm{S}\mathrm{p}(1)$ bundles over quaternionic projective space.
