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…
