HIGHLIGHTS
- who: Yun-Xian Chen et al. from the Physics and Astronomy College, China West Normal University, Nanchong, China have published the Article: The Observational Shadow Features of a Renormalization Group Improved Black Hole Considering Spherical Accretions, in the Journal: Symmetry 2022, 14, 1959. of /2022/
- what: The authors investigate the black hole shadow and photon sphere when an RGI black hole is surrounded by thin spherical accretions, and further reveal the effects of the renormalization group parameters on the black hole shadow. The authors briefly introduce the photon orbits of RGI black holes and their . . .
