A new analytical model of magnetofluids surrounding rotating black holes
Yehui Hou, Zhenyu Zhang, Minyong Guo +1
In this study, we develop a simplified magnetofluid model in the framework of GRMHD. We consider an ideal, adiabatic fluid composed of two components, ions and electrons, having a…
Observational signatures of rotating black holes in the semiclassical gravity with trace anomaly
Zhenyu Zhang, Yehui Hou, Minyong Guo
In a recent work by Fernandes [arXiv:2305.10382], an exact stationary and axisymmetric solution was discovered in semiclassical gravity with type-A trace anomaly, identified as a q…
Polarized images of charged particles in vortical motions around a magnetized Kerr black hole
Zhenyu Zhang, Yehui Hou, Zezhou Hu +2
In this work, we study the images of a Kerr black hole (BH) immersed in uniform magnetic fields, illuminated by the synchrotron radiation of charged particles in the jet. We partic…
Electromagnetic effects on charged particles in NHEK
Yehui Hou, Zhenyu Zhang, Minyong Guo +1
We investigate the motions of charged particles in the near horizon region of an extreme Kerr black hole with weak electromagnetic fields. There is an enhanced symmetry in the NHEK…
