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

Static and stationary regular black holes are examined under a minimal set of requirements
consisting of (i) the existence of a well defined event horizon and (ii) the weak energy …

In this paper, we study the dynamics of the shock cone formed around a hairy Kerr black
hole due to Bondi–Hoyle–Lyttleton (BHL) accretion and investigate the quasi-periodic …

Recently, Contreras et al.[Phys. Rev. D 103, 044020 (2021) PRVDAQ 2470-0010
10.1103/PhysRevD. 103.044020] introduced a new type of black hole, called the hairy Kerr …

The weak cosmic censorship conjecture, since its proposal, has always been a controversial
hypothesis, but its significance in astrophysics is undeniable. For a regular black hole, its …

In this paper, 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 …

We investigate the geodesic motions of timelike particles around a static hairy black hole
with conformally coupled scalar field. We mainly focus on the effects of the scalar charge …

We investigate the differences between a test timelike particle's motions around scale-
dependent Planck stars and its motions around renormalization group improved …

A hairy Schwarzschild black hole describes the deformation of Schwarzschild black hole
with an exponent correction due to the introducing of additional sources. Inspired by the …

In the electromagnetic channel, chaotic gravitational lensing is a peculiar phenomenon in
strong gravitational lensing. In this study, we analyze the properties and emergence of …
