Shadows of black hole surrounded by anisotropic fluid in Rastall theory
Rahul Kumar, Balendra Pratap Singh, Md Sabir Ali +1
Due to the gravitational lensing effect, a black hole casts a shadow larger than its horizon over a bright background, and the shape and size can be calculated. The Event Horizon T…
Rotating black hole in Rastall theory
Rahul Kumar, Sushant G. Ghosh
Rotating black hole solutions in theories of modified gravity are important as they offer an arena to test these theories through astrophysical observation. The non-rotating black…
Lovelock black holes surrounded by quintessence
Sushant G. Ghosh, Sunil D. Maharaj, Dharmanand Baboolal +1
Lovelock gravity consisting of the dimensionally continued Euler densities is a natural generalization of general relativity to higher dimensions such that equations of motion are…
Noncommutative geometry inspired rotating black string
Dharm Veer Singh, Md Sabir Ali, Sushant G. Ghosh
Noncommutativity is an idea dating back to the early times of Quantum Mechanics and that string theory induced noncommutative (NC) geometry which provides an effective framework to…
Shadow of Schwarzschild-Tangherlini black holes
Balendra Pratap Singh, Sushant G. Ghosh
We study the shadow cast by the H Schwarzschild-Tangherlini black hole, and analytically calculate the influence of extra dimensions on the shadow of a black hole. A black hole…
Shadows of rotating five-dimensional charged EMCS black holes
Muhammed Amir, Balendra Pratap Singh, Sushant G. Ghosh
Higher dimensional theories admit astrophysical objects like supermassive black holes, which are rather different from standard ones, and their gravitational lensing features devia…
