Observational appearances of an inner extremal regular black hole illuminated by various accretion flows

Dan Zhang, Guoyang Fu, Xi-Jing Wang +3

This paper investigates the observational appearances of an inner extremal regular black hole(IERBH) illuminated by various types of accretion models. The study reveals that when t…

Images of hairy Reissner-Nordström black hole illuminated by static accretions

Yuan Meng, Xiao-Mei Kuang, Xi-Jing Wang +2

We investigate the shadow and optical appearance of the hairy Reissner-Nordström (RN) black hole illuminated by two toy models of static accretion. The hairy RN black hole was cons…

Perturbations of massless external fields in Horndeski hairy black hole

Zhen-Hao Yang, Yun-He Lei, Xiao-Mei Kuang +1

In this paper, we study the propagations of external fields in Horndeski theory, including the scalar field, electromagnetic field and Dirac field. We extensively explore the quasi…

Black holes with scalar hair: Extending from and beyond the Schwarzschild solution

Xi-Jing Wang, Guoyang Fu, Peng Liu +3

We construct novel scalarized black hole (BH) solutions beyond the general relativity (GR) framework. These scalarized BH solutions are extended from the Schwarzschild one and the…

Images from disk and spherical accretions of hairy Schwarzschild black holes

Yuan Meng, Xiao-Mei Kuang, Xi-Jing Wang +2

A hairy Schwarzschild black hole describes the deformation of Schwarzschild black hole due to including additional sources. It is found that depending on the hairy parameters, the…

Diagnosing quantum phase transition via holographic entanglement entropy at finite temperature

Huajie Gong, Guoyang Fu, Peng Liu +3

We investigate the behavior of the holographic entanglement entropy (HEE) in proximity to the quantum critical points (QCPs) of the metal-insulator transition (MIT) in the Einstein…
