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…
Rings and images of Horndeski hairy black hole illuminated by various thin accretions
Xi-Jing Wang, Xiao-Mei Kuang, Yuan Meng +2
We analyze the light rays around a static hairy black hole in Horndeski gravity with the use of ray-tracing procedure. We find that a stronger Horndeski hairy parameter corresponds…
Detecting vector charge with extreme mass ratio inspirals onto Kerr black holes
Chao Zhang, Hong Guo, Yungui Gong +1
Extreme mass ratio inspirals (EMRIs) are excellent sources for space-based observatories to explore the properties of black holes and test no-hair theorems. We consider EMRIs with…
Black hole images: A Review
Songbai Chen, Jiliang Jing, Wei-Liang Qian +1
In recent years, unprecedented progress has been achieved regarding black holes' observation through the electromagnetic channel. The images of the supermassive black holes M87$^{*…
Photon region and shadow of a rotating 5D black string
Zi-Yu Tang, Xiao-Mei Kuang, Bin Wang +1
To explore the possible clues for the extra dimension from the Event Horizon Telescope (EHT) observations, we study the shadow of the rotating 5D black string in General Relativity…
Rotating -dimensional Black Holes in Einstein-Maxwell-Dilaton Theory
Thanasis Karakasis, Eleftherios Papantonopoulos, Zi-Yu Tang +1
We consider Einstein-Maxwell-Dilaton theory in -dimensions where the coupling between the scalar field and the Maxwell invariant is the dilatonic coupling $f(ϕ) = \exp (-2αϕ…
The length of a compact extra dimension from black hole shadow
Zi-Yu Tang, Xiao-Mei Kuang, Bin Wang +1
Plenty of efforts have been made to explore the black string and its instability, but the fate of the black strings with fewer extra dimensions is still inconclusive. Now starting…
Constraining a modified gravity theory in strong gravitational lensing and black hole shadow observations
Xiao-Mei Kuang, Zi-Yu Tang, Bin Wang +1
We study the strong gravitational lensing effect around rotating black holes in different gravity theories. By calculating the deflection angle of strong gravitational lensing, we…
