We use exceptional field theory to systematically study all possible consistent truncations around any M-theory half-maximal vacua of the warped product form AdS5 × M 3 × S 2 × S 1, with M 3 a three-dimensional manifold. We show that, for any of these vacua, only truncations with at most three vector multiplets are consistent. Furthermore, the possible gaugings are restricted to be either SU(2) × U(1) or ISO(3) × U(1) where, in the first case, the U(1) factor can have different embeddings…

Kaluza-Klein spectrometry for AdS3 vacua
We use exceptional field theory to compute Kaluza-Klein mass spectra around AdS3 vacua that sit in half-maximal gauged supergravity in three dimensions. The formalism applies to any vacuum that
