Testing charged Simpson-Visser-AdS spacetimes with twin-peak QPOs
Saeed Ullah Khan, Javlon Rayimbaev, Muhammad Zahid +3
In this manuscript, we study circular geodesics and twin-peak high-frequency quasi-periodic oscillations (HF-QPOs) in the charged Simpson--Visser--anti-de Sitter (AdS) spacetime, w…
Charged Simpson-Visser-AdS spacetime: QPOs and observational constraints
Saeed Ullah Khan, Javlon Rayimbaev, Muhammad Zahid +3
In this article, we examine particle dynamics and Quasi-periodic oscillations within a charged Simpson-Visser-Anti-de Sitter (AdS) spacetime. We first analyze the behavior of the m…
Rotating black holes surrounded by PFDM in STVG: Shadows and eikonal quasinormal modes
Muhammad Zahid, Zhiling Liu, Saeed Ullah Khan +1
We investigate the optical and dynamical properties of a rotating black hole in scalar--tensor--vector gravity (STVG) surrounded by perfect fluid dark matter (PFDM). Starting from…
Shadow cast and center of mass energy in a charged Gauss-Bonnet-AdS black hole
Muhammad Zahid, Saeed Ullah Khan, Jingli Ren
This work is devoted to the exploration of shadow cast and center of mass energy in the background of a 4-dimensional charged Gauss-Bonnet AdS black hole. On investigating particle…
