Black Hole Quasi-Periodic Oscillations in the Presence of Gauss-Bonnet Trace Anomaly
Rupam Jyoti Borah, Umananda Dev Goswami
We investigate the effects of the Gauss-Bonnet (GB) gravitational trace anomaly on the circular motion of test particles around black holes (BHs) and its implications for quasi-per…

Quasinormal Modes and Shadows of Black Holes in Infinite Derivative Theory of Gravity
Rupam Jyoti Borah, Umananda Dev Goswami
In this work, we study the quasinormal modes (QNMs) and shadow of a Schwarzschild black hole (BH) with higher-order metric corrections, in the framework of the Infinite Derivative…

Strong Lensing Effect and Quasinormal Modes of Oscillations of Black Holes in Gravity Theory
Gayatri Mohan, Ronit Karmakar, Rupam Jyoti Borah +1
In this work, we analyze the strong lensing phenomenon and quasinormal modes (QNMs) in the case of black holes (BHs) surrounded by fluids within the framework of gravity,…
