Ellis-Bronnikov wormholes with NUT charge
Masato Nozawa, Tomohiro Harada, Keisuke Nakashi
We construct an exact NUT-charged generalization of the Ellis-Bronnikov wormhole in the Einstein-phantom-scalar system. The solution is stationary, asymptotically locally flat at b…
Wormhole metric
Masato Nozawa, Takashi Torii
The C-metric in vacuum general relativity describes a pair of accelerated black holes supported by conical singularity. In this paper, we present a new family of exact solutions to…
New family of C-metrics in gauged supergravity
Masato Nozawa, Takashi Torii
We present a new family of charged C-metrics in gauged supergravity in four dimensions. The double Wick rotation of the C-metric allows us to bring our solution into a…
An alternative to the Simon tensor
Masato Nozawa
The Simon tensor gives rise to a local characterization of the Kerr-NUT family in the stationary class of vacuum spacetimes. We find that a symmetric and traceless tensor in the qu…
Static spacetimes haunted by a phantom scalar field III: asymptotically (A)dS solutions
Masato Nozawa
The static and spherically symmetric solutions in -dimensional Einstein-phantom-scalar system fall into three family: (i) the Fisher solution, (ii) the Ellis-Gibbons solu…
Static spacetimes haunted by a phantom scalar field II: dilatonic charged solutions
Masato Nozawa
We present a method to generate static solutions in the Einstein-Maxwell system with a (phantom) dilaton field in -dimensions, based upon the symmetry of the target space…
