Magnetized Kerr-Taub-NUT spacetime and Kerr/CFT correspondence

Abstract

We present a new solution in Einstein-Maxwell theory which can be considered as the magnetized version of Kerr-Taub-NUT solution. Some properties of the spacetime are discussed. We also compute the entropy of extremal black hole in the spacetime by using the Kerr/CFT correspondence approach.

Magnetized Kerr-Newman-Taub-NUT spacetimes

“…A number of aspects of the known magnetized black hole solutions had been reported in literature [22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38], and this shows the importance of such solution in shaping our knowledge on gravity. The most recent ones are the magnetization to Reissner-Nordstrom -Taub-NUT [39] and Kerr-Taub-NUT [40]. The work presented in this paper extends the previous works to magnetizing the Kerr-Newman-Taub-NUT (KNTN) spacetimes, which we refer to as the Melvin-Kerr-Newman-Taub-Nut (MKNTN) spaetimes.…”
