N = 31, D = 11
We show that eleven-dimensional supergravity backgrounds with thirty one supersymmetries, N = 31, admit an additional Killing spinor and so they are locally isometric to maximally supersymmetric ones. This rules out the existence of simply connected eleven-dimensional supergravity preons. We also show that N = 15 solutions of type I supergravities are locally isometric to Minkowski spacetime. T...
متن کاملFirst Detection of Molecular Gas in the Shells of CenA ⋆
Shells are faint arc-like stellar structures, which have been observed around early type galaxies and are thought to be the result of an interaction. HI gas has recently been detected in shells, a surprising result in view of the theoretical predictions that most of the gas should decouple from stars and fall into the nucleus in such interactions. Here we report the first detection of molecular...

The Cu(II) atom in the title salt, [Cu(C(10)H(24)N(4))(H(2)O)(2)][CH(3)(CH(2))(8)CO(2)](2)·2H(2)O, is chelated by the four N atoms of the 1,4,8,11-tetra-aza-cyclo-tetra-decane (cyclam) ligand and is coordinated by two water mol-ecules in a Jahn-Teller-type tetra-gonally distorted octa-hedral geometry. The Cu(II) atom lies on a center of inversion. The cations, anions and uncoordinated water mol...

The title compound, [Cu(C(10)H(24)N(4))(H(2)O)(2)][CH(3)(CH(2))(10)CO(2)](2)·2H(2)O, consists of one cationic copper(II) complex, two dodeca-noate anions and two water solvent mol-ecules. The Cu(II) atom is located on an inversion center and is chelated by the four aza N atoms of the neutral 1,4,8,11-tetra-aza-cyclo-tetra-decane (cyclam) ligand and by two water mol-ecules in axial positions, gi...
