abstract
We prove an old conjecture by Duff, Nilsson, Pope and Warner asserting that the NS-NS sector of supergravity (and more general the bosonic string) allows for a consistent Pauli reduction on any d-dimensional group manifold G, keeping the full set of gauge bosons of the G x G isometry group of the bi-invariant metric on G. The main tool of the construction is a particular generalised Scherk-Schwarz reduction ansatz in double field theory which we explicitly construct in terms of the group's Killing vectors. Examples include the consistent reduction from ten dimensions on $S^3\times S^3$ and on similar product spaces. The construction is another example of globally geometric non-toroidal compactifications inducing non-geometric fluxes.

Scale separation on AdS$_3\times S^3$ with and without supersymmetry
The complete Kaluza-Klein spectrum of six-dimensional Salam-Sezgin supergravity on AdS3 times a squashed three-sphere is computed; in the large-squashing limit, all but a small set of low-energy fields acquire infinite mass.

Consistent Warped $\mathbb R\times T^{1,1}$ Reduction of Heterotic Supergravity
A warped R × T^{1,1} vacuum of heterotic supergravity preserves 1/4 supersymmetry and reduces consistently to N=1, D=4 supergravity with SU(2)×SU(2) Yang-Mills fields of geometric origin.
