Taub-NUT as gravitational dyon with torsion
Dmitri Gal'tsov, Rostom Karsanov
We show that the Levi-Civita connection for the Taub-NUT metric is singular on Misner strings and generates an Einstein tensor containing the squares of the delta function. This ca…
Gravielectric and gravimagnetic fluxes in nutty black holes
Dmitri Gal'tsov, Rostom Karsanov
We introduce the gravielectric (GE) and gravimagnetic (GM) fields in stationary spacetime using the Komar two-form and its dual. This opens the way to extend the Komar-Tomimatsu de…
Charged nutty black holes are hairy
Dmitri Gal'tsov, Rostom Karsanov
We uncover the physical nature of the electric and magnetic monopoles discovered by McGuire and Ruffini on Misner strings accompanying charged nutty black holes, showing that these…
Gauged supergravities: solutions with Killing tensor
Dmitri Gal'tsov, Rostom Karsanov
We perform full integration of the stationary axisymmetric Einstein-Maxwell-dilaton-axion (EMDA) theory with and without potential using a recently proposed generalization of Carte…
