The Optical Appearance of Charged Four-Dimensional Gauss-Bonnet Black Hole with Strings Cloud and Non-Commutative Geometry Surrounded by Various Accretions Profiles

Xiao-Xiong Zeng, M. Israr Aslam, Rabia Saleem

Thanks for the releasing image of supermassive black holes (BHs) by the event horizon telescope (EHT) at the heart of the galaxy. After the discovery of this mysterious objec…

Influence of quintessence dark energy on the shadow of black hole

Xiao-Xiong Zeng, Hai-Qing Zhang

We investigate the effects of quintessence dark energy on the shadows of black hole, surrounded by various profiles of accretions. For the thin disk accretion, the images of the bl…

Shadows and photon spheres with spherical accretions in the four-dimensional Gauss-Bonnet black hole

Xiao-Xiong Zeng, Hai-Qing Zhang, Hongbao Zhang

We investigate the shadows and photon spheres of the four-dimensional Gauss-Bonnet black hole with the static and infalling spherical accretions. We show that for both cases, the s…

The weak cosmic censorship conjecture and thermodynamics in the quintessence AdS black hole under charge particle absorption

Ke-Jian He, Xin-Yun Hu, Xiao-Xiong Zeng

Considering the cosmological constant as the pressure, we mainly study the laws of thermodynamics and weak cosmic censorship conjecture in the Reissner-Nordström-AdS black hole sur…

Thermodynamics and weak cosmic censorship conjecture of the BTZ black holes in the extended phase space

Xiao-Xiong Zeng, Yi-Wen Han, De-You Chen

As charged fermions drop into the BTZ black holes, we check the laws of thermodynamics and weak cosmic censorship conjecture in the normal phase space and extended phase space, whe…
