Euclidean Supergravity in Five Dimensions
Wafic A. Sabra, Owen Vaughan
We construct a 5D, N = 2 Euclidean theory of supergravity coupled to vector multiplets. Upon reducing this theory over a circle we recover the action of 4D, N = 2 Euclidean supergr…
Special Geometry of Euclidean Supersymmetry IV: the local c-map
Vicente Cortés, Paul Dempster, Thomas Mohaupt +1
We consider timelike and spacelike reductions of 4D, N = 2 Minkowskian and Euclidean vector multiplets coupled to supergravity and the maps induced on the scalar geometry. In parti…
10D to 4D Euclidean Supergravity over a Calabi-Yau three-fold
Wafic Sabra, Owen Vaughan
We dimensionally reduce the bosonic sector of 10D Euclidean type IIA supergravity over a Calabi-Yau three-fold. The resulting theory describes the bosonic sector of 4D, N = 2 Eucli…
Non-extremal black hole solutions from the c-map
David Errington, Thomas Mohaupt, Owen Vaughan
We construct new static, spherically symmetric non-extremal black hole solutions of four-dimensional supergravity, using a systematic technique based on dimensional re…
Rotating black holes in 4d gauged supergravity
Alessandra Gnecchi, Kiril Hristov, Dietmar Klemm +2
We present new results towards the construction of the most general black hole solutions in four-dimensional Fayet-Iliopoulos gauged supergravities. In these theories black holes c…
Nonextremal black holes in gauged supergravity and the real formulation of special geometry II
Dietmar Klemm, Owen Vaughan
In arXiv:1207.2679 a new prescription for finding nonextremal black hole solutions to N=2, D=4 Fayet-Iliopoulos gauged supergravity was presented, and explicit solutions of various…
Non-extremal black holes from the generalised r-map
Thomas Mohaupt, Owen Vaughan
We review the timelike dimensional reduction of a class of five-dimensional theories that generalises 5D, N = 2 supergravity coupled to vector multiplets. As an application we cons…
Nonextremal black holes in gauged supergravity and the real formulation of special geometry
Dietmar Klemm, Owen Vaughan
We give a rather general recipe for constructing nonextremal black hole solutions to N=2, D=4 gauged supergravity coupled to abelian vector multiplets. This problem simplifies cons…
Developments in special geometry
Thomas Mohaupt, Owen Vaughan
We review the special geometry of N = 2 supersymmetric vector and hypermultiplets with emphasis on recent developments and applications. A new formulation of the local c-map based…
The Hesse potential, the c-map and black hole solutions
Thomas Mohaupt, Owen Vaughan
We present a new formulation of the local c-map, which makes use of the real formulation of special Kahler geometry and the associated Hesse potential. As an application we use the…
Non-extremal Black Holes, Harmonic Functions, and Attractor Equations
T. Mohaupt, O. Vaughan
We present a method which allows to deform extremal black hole solutions into non-extremal solutions, for a large class of supersymmetric and non-supersymmetric Einstein-Vector-Sca…
