Shadow of rotating black hole surrounded by dark matter
Haiyuan Feng, Ziqiang Cai, Rong-Jia Yang +1
Dark matter (DM), a fundamental cosmic component, motivates the study of its influence on black hole (BH) shadows, especially for spinning BHs confirmed by EHT observations. This w…
Images of shadow and thin accretion disk around Bardeen black hole surrounded by perfect fluid dark matter
Haiyuan Feng, Ziqiang Cai, Hao-Peng Yan +2
We investigate the shadow and optical appearance of Bardeen black hole (BH) immersed in perfect fluid dark matter (PFDM). Using EHT observations of M87* and Sgr A*, we constrain th…
Rotating Charged Black Holes with Scalar Hair Constructed via the Newman-Janis Algorithm: Accretion Disk Structure and Shadow Characteristics
Ziqiang Cai, Zhenglong Ban, Qi-Qi Liang +2
In this paper, we generate a rotating charged black hole (BH) with scalar hair via the Newman--Janis algorithm (NJA) and study its thin accretion disk and shadow. The structure of…
Shadow and thin accretion disk around Ayón-Beato-García black hole coupled with cloud of strings
Ziqiang Cai, Zhenglong Ban, Lu Wang +2
In this paper, we investigate the shadow and thin accretion disk around Ayón-Beato-García (ABG) black hole (BH) coupled with a cloud of strings (CS), characterized by the nonlinear…
Probing Einstein-Maxwell-Scalar Black hole via Thin Accretion Disks and Shadows with EHT Observations of M87* and Sgr A*
Yingdong Wu, Ziqiang Cai, Zhenglong Ban +2
We investigated the shadows and thin accretion disks of Einstein-Maxwell-Scalar (EMS) black hole. Firstly, we investigated the influence of EMS parameters on the black hole shadow…
Thin accretion disk around Schwarzschild-like black hole in bumblebee gravity
Ziqiang Cai, Zhenglong Ban, Lu Wang +2
The physical properties and optical appearance of a thin accretion disk surrounding a Schwarzschild-like black hole (BH) are investigated within the framework of bumblebee gravity.…
