Quasinormal modes of scalar and Maxwell field perturbations coupled to the Einstein tensor in generalized Nariai spacetimes
Xin Qin, Xiongying Qiao, Qiyuan Pan +3
We investigate the quasinormal modes of scalar and Maxwell field perturbations coupled to the Einstein tensor in generalized Nariai spacetimes. Our results show that, for both type…

Thin accretion disk around a Kerr black hole immersed in swirling universes
Yuxin Ouyang, Xuan Zhou, Songbai Chen +1
We have studied the properties of thin accretion disks around swirling-Kerr black holes, which own an extra swirling parameter describing the rotation of the immersed universe. Our…
