Deformed and twisted black holes with NUTs

Krtouš, P.; Kubizňák, D.; Frolov, V. P.; Kolář, I.

We construct a new class of vacuum black hole solutions whose geometry is
deformed and twisted by the presence of NUT charges. The solutions are
obtained by ‘unspinning’ the general Kerr-NUT-(A)dS spacetimes, effectively
switching off some of their rotation parameters. The resulting geometry has a
structure of warped space with the Kerr-like Lorentzian part warped to a
Euclidean metric of a deformed and/or twisted sphere, with the deformation
and twist characterized by the ‘Euclidean NUT’ parameters. In the absence of
NUTs, the solution reduces to a well known Kerr-(A)dS black hole with
several rotations switched off. New geometries inherit the original symmetry
of the Kerr-NUT-(A)dS family, namely, they possess the full Killing tower of
hidden and explicit symmetries. As expected, for vanishing NUT, twist, and
deformation parameters, the symmetry is further enlarged.
