Shadow cast by a rotating and nonlinear magnetic-charged black hole in perfect fluid dark matter
Tian-Chi Ma, He-Xu Zhang, Peng-Zhang He +3
We derived an exact solution of the spherically symmetric Hayward black hole surrounded by perfect fluid dark matter (PFDM). By applying the Newman-Janis algorithm, we generalized…

Shadows of rotating Hayward-de Sitter black holes with astrometric observables
Peng-Zhang He, Qi-Qi Fan, Hao-Ran Zhang +1
Motivated by recent work on rotating black hole shadow [Phys. Rev. D101, 084029 (2020)], we investigate the shadow behaviors of rotating Hayward-de Sitter black hole for static obs…

The cosmological constant from space-time discreteness
Qi-Qi Fan, Cong Li, Hao-Ran Zhang +2
We regard the background of space-time as a physical system composed of discrete volume elements at the Planck scale and get the internal energy of space-time by Debye model. A tem…
