On the Stability of Warped Anti-de Sitter Spaces in Supergravity
S. Maurelli, R. Noris, M. Oyarzo +3
We discuss the perturbative stability of warped anti-de Sitter (WAdS) spaces in three-dimensional gauged supergravity. To this end, we first derive the analogue of the Breitenl…
Supersymmetric Moduli Space and Vacua with Vector Fields in Gauged Supergravity
Andrés Anabalón, Stefano Maurelli, Marcelo Oyarzo +1
When fermions are taken to be anti-periodic along a spacelike in , certain ground states of the supergravity theory are described by AdS-soliton-like spacetimes. We st…
Deforming in Type IIB Supergravity
Stefano Maurelli, Ruggero Noris, Marcelo Oyarzo +1
We discuss some new results on the construction of supersymmetric solutions of Type IIB supergravity of the form , and ${\rm…
Warped-AdS Near-Horizon Geometries From TsT Transformations
S. Maurelli, R. Noris, M. Oyarzo +1
We provide a string theory realisation of a two-parameter family of Type IIB supergravity solutions of the form , as near-horizon geometr…
On U-Folds and Their Construction
Stefano Maurelli, Ruggero Noris, Marcelo Oyarzo +1
We review a general paradigm for constructing U-fold backgrounds in (dimensionally reduced) Type IIB superstring theory, of the form , with a m…
Supersymmetric Warped Solutions from Type IIB Orientifold Reduction
S. Maurelli, R. Noris, M. Oyarzo +2
We construct a family of supersymmetric solutions in Type IIB supergravity of the form , where and denote a war…
The Instability of Low-Temperature Black Holes in Gauged Supergravity
Andrés Anabalón, Stefano Maurelli, Marcelo Oyarzo +1
We consider the static planar black hole solutions in the STU model of the gauged supergravity in four dimensions. We give a straightforward derivation of the equat…
