Symmetry operators for the conformal wave equation in rotating black hole spacetimes

Finnian Gray, Tsuyoshi Houri, David Kubiznak +1

We present covariant symmetry operators for the conformal wave equation in the (off-shell) Kerr-NUT-AdS spacetimes. These operators, that are constructed from the principal Killing…

Thermodynamics of Rotating NUTty Dyons

Alvaro Ballon Bordo, Finnian Gray, David Kubiznak

We extend the work on thermodynamics of Lorentzian NUTty solutions, by including simultaneously the effect of rotation and electromagnetic charges. Due to the fact that Misner stri…

Conformally Coupled Scalar in Rotating Black Hole Spacetimes

Finnian Gray, Ian Holst, David Kubiznak +3

We demonstrate separability of conformally coupled scalar field equation in general (off-shell) Kerr-NUT-AdS spacetimes in all dimensions. The separability is intrinsically charact…

Massive vector fields in Kerr--Newman and Kerr--Sen black hole spacetimes

Ramiro Cayuso, Oscar J. C. Dias, Finnian Gray +5

The superradiant instability modes of ultralight massive vector bosons are studied for weakly charged rotating black holes in Einstein--Maxwell gravity (the Kerr--Newman solution)…

Principal Tensor Strikes Again: Separability of Vector Equations with Torsion

Ramiro Cayuso, Finnian Gray, David Kubiznak +3

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 pro…

The First Law for Rotating NUTs

Alvaro Ballon Bordo, Finnian Gray, Robie A. Hennigar +1

We address a long-standing problem of describing the thermodynamics of rotating Taub--NUT solutions. The obtained first law is of full cohomogeneity and allows for asymmetric distr…
