Domain Walls of D=8 Gauged Supergravities and their D=11 Origin (2003)
Alonso-Alberca, N, Bergshoeff, E A, Gran, U G, Linares, R, OrtÃn, Tomas, Roest, D
Performing a Scherk-Schwarz dimensional reduction of D=11 supergravity on a three-dimensional group manifold we construct five D=8 gauged maximal supergravities whose gauge groups are the...

The Near-Horizon Limit of the Extreme Rotating d=5 Black Hole as a Homogenous Spacetime (2002)
Alonso-Alberca, N., Lozano-Tellechea, E., Ortin, T.
We show that the spacetime of the near-horizon limit of the extreme rotating d=5 black hole, which is maximally supersymmetric in N=2,d=5 supergravity for any value of the rotation parameter j in...
Alonso-Alberca, N., Lozano-Tellechea, E., Ortin, T.
We show how the Killing spinors of some maximally supersymmetric supergravity solutions whose metrics describe symmetric spacetimes (including $AdS,AdS\times S$ and H$pp$-waves) can be easily...
Alonso-Alberca, N., Meessen, P., Ortin, T.
The so-called ``massive 11-dimensional supergravity'' theory gives, for one Killing vector, Romans' massive 10-dimensional supergravity in 10 dimensions, for two Killing vectors an Sl(2,Z) multiplet...
Supersymmetric Brane-Worlds (2000)
Alonso-Alberca, N., Meessen, P., Ortin, T.
We present warped metrics which solve Einstein equations with arbitrary cosmological constants in both in upper and lower dimensions. When the lower-dimensional metric is the maximally symmetric one...
Supersymmetry of topological Kerr-Newmann-Taub-NUT-aDS spacetimes (2000)
Alonso-Alberca, N., Meessen, P., Ortin, T.
We extend the topological Kerr-Newman-aDS solutions by including NUT charge and find generalizations of the Robinson-Bertotti solution to the negative cosmological constant case with different...
Kaehler forms and cosmological solutions in type II supergravities (2000)
Alonso-Alberca, N., Meessen, P.
We consider cosmological solutions to type II supergravity theories where the spacetime is split into a FRW universe and a K\"ahler space, which may be taken to be Calabi-Yau. The various 2-forms...
