The paper “N=4 near-horizon geometries in D=11 supergravity“, co-authored by Daniele Farotti and Jan Gutowski, has been published in the Journal of High Energy Physics. A link to the published version is here. The paper investigates the additional geometric conditions imposed on the near-horizon region of supersymmetric extremal black holes in eleven dimensional supergravity when there is double the minimal amount of supersymmetry.
