Imaging a Semi-Analytical Jet model Generated by 3D GRMHD Simulation
Ye Shen, Yehui Hou, Zhong-Ying Fan +2
Employing 3D GRMHD simulation, we study the images of a geometrically thin jet, whose emissions concentrate on its surface, for accretion system surrounding a central spinning BH.…
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…
How different are shadows of compact objects with and without horizons?
Xiangyu Wang, Yehui Hou, Minyong Guo
In this work, we theoretically assume that a compact object (CO) can have a dark surface so that the CO is simplified to have no emissions and reflections. Considering that the rad…
