Generalized Couch-Torrence symmetry for rotating extremal black holes in maximal supergravity
Mirjam Cvetič, Christopher N. Pope, Aritra Saha
Izvirni znanstveni članek
Oznake: Kvantna logika;Fizika elementarnih delcev;Črne luknje;
he extremal Reissner-Nordstrom black hole admits a conformal inversion symmetry, in which the metric is mapped into itself under an inversion of the radial coordinate combined with a conformal rescaling. In the rotating generalization, Couch and Torrence showed that the Kerr- Newman metric no longer ...

Conformal symmetries for extremal black holes with general asymptotic scalars in STU supergravity
Mirjam Cvetič, Christopher N. Pope, Aritra Saha
Izvirni znanstveni članek
Oznake: black holes;extended supersymmetry;supergravity models;string theory;
We present a construction of the most general BPS black holes of STU supergravity (N = 2 supersymmetric D = 4 supergravity coupled to three vector supermultiplets) with arbitrary asymptotic values of the scalar fields. These solutions are obtained by acting with a subset of the global symmetry gener ...

Gaussian null coordinates for rotating charged black holes and conserved charges
Mirjam Cvetič, Christopher N. Pope, Aritra Saha, Alejandro Satz
Izvirni znanstveni članek
Oznake: supergravitiy;flat spacetime;black hole;four-dimensional rotating;metrics;
Motivated by the study of conserved Aretakis charges for a scalar field on the horizon of an extremal black hole, we construct the metrics for certain classes of four-dimensional and five-dimensional extremal rotating black holes in Gaussian null coordinates. We obtain these as expansions in powers ...
