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…
Mirror actuation design for the interferometer control of the KAGRA gravitational wave telescope
Yuta Michimura, Tomofumi Shimoda, Takahiro Miyamoto +36
KAGRA is a 3-km cryogenic interferometric gravitational wave telescope located at an underground site in Japan. In order to achieve its target sensitivity, the relative positions o…
Accretion onto a noncommutative geometry inspired black hole
Rahul Kumar, Sushant G. Ghosh
The spherically symmetric accretion onto a noncommutative (NC) inspired Schwarzschild black hole is treated for a polytropic fluid. The critical accretion rate , sonic spe…
