Photon emissions from Kerr equatorial geodesic orbits
Yanming Su, Minyong Guo, Haopeng Yan +1
We consider the light emitters moving freely along the geodesics on the equatorial plane near a Kerr black hole and study the observability of these emitters. To do so, we assume t…

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…
