Analytic thin disks and rings in a class of nonasymptotically flat static spacetimes
Shokoufe Faraji, Ruijing Tang
External matter distributions can substantially reshape the strong field environment of compact objects, yet this effect is usually neglected in idealized isolated models. In this…

Quasinormal modes of rotating black holes beyond general relativity in the WKB approximation
Ruijing Tang, Nicola Franchini, Sebastian H. Völkel +1
Exploring gravitational theories beyond general relativity (GR) with black hole (BH) spectroscopy requires accurate and flexible methods for computing their quasinormal mode (QNM)…

Exploring Born-Infeld f(T) teleparallel gravity through accretion disk dynamics
Ruijing Tang, Shokoufe Faraji, Niayesh Afshordi
Teleparallel Born-Infeld gravity (TBI) is a modified theory of gravity that aims to maintain second order field equations, leading to alternative scenarios for strong gravity and c…
