Shadow of a disformal Kerr black hole in quadratic DHOST theories
Fen Long, Songbai Chen, Mingzhi Wang +1
We have studied the shadow of a disformal Kerr black hole with an extra deformation parameter, which belongs to non-stealth rotating solutions in quadratic Degenerate Higher Order…
Shadow of a rotating squashed Kaluza-Klein black hole
Fen Long, Jieci Wang, Songbai Chen +1
We study the shadow of a rotating squashed Kaluza-Klein (KK) black hole and the shadow is found to possess distinct properties from those of usual rotating black holes. It is shown…
Electromagnetic emissions from near-horizon region of an extreme Kerr-Taub-Nut black hole
Fen Long, Songbai Chen, Jieci Wang +1
We have studied electromagnetic line emissions from near-horizon region in the extremal Kerr-Taub-NUT black hole spacetime and then probe the effects of NUT charge on the electroma…
Energy extraction from a Konoplya-Zhidenko rotating non-Kerr black hole
Fen Long, Songbai Chen, Shangyun Wang +1
We have investigated the properties of the ergosphere and the energy extraction by Penrose process in a Konoplya-Zhidenko rotating non-Kerr black hole spacetime. We find that the e…
