Conformal invariance, complex structures and the Teukolsky connection
(IOP Publishing, 2018-07-23)
We show that the Teukolsky connection, which defines generalized wave operators governing the behavior of massless fields on Einstein spacetimes of Petrov type D, has its origin in a distinguished conformally and GHP ...
Generalized wave operators, weighted Killing fields, and perturbations of higher dimensional spacetimes
(IOP Publishing, 2018-03-09)
We present weighted covariant derivatives and wave operators for perturbations of certain algebraically special Einstein spacetimes in arbitrary dimensions, under which the Teukolsky and related equations become weighted ...

Principal tensor strikes again: Separability of vector equations with torsion
(2019-08-10)
Many black hole spacetimes with a 3-form field exhibit a hidden symmetry encoded in a torsion generalization of the principal Killing–Yano tensor. This tensor determines basic properties of such black holes while also ...
Conformally coupled scalar in rotating black hole spacetimes
(Amer Physical Soc, 2020-04-15)
We demonstrate separability of conformally coupled scalar field equations in general (off-shell) Kerr-Newman-Unti-Tamburino-anti-de Sitter spacetimes in all dimensions. The separability is intrinsically characterized by ...

We demonstrate separability of conformally coupled scalar field equations in general (off-shell) Kerr - Newman-Unti-Tamburino - anti-de Sitter spacetimes in all dimensions. The separability is intrinsically characterized ...
Simetrías ocultas, twistors y estabilidad de campos lineales en agujeros negros
(2018-05-11)
En 4 dimensiones, nuestros resultados valen para perturbaciones de toda la clase de espacio-tiempos Einstein de tipo Petrov D, que incluye la métrica de Kerr-(A)dS que representa un agujero negro rotante con constante ...
