Onset of Chaos and Orbital Instabilities around Rotating Weyl Black Holes
Shubham Kala, M. Yousaf, Pradeep Singh +3
We investigate nonlinear photon motion in the vicinity of a rotating black hole (BH) within Weyl conformal gravity (WCG) by employing Poincare sections, Lyapunov exponents, Fast Ly…

Disformal Kerr Imprints on BHL Accretion: Shock Morphology, PSD Signatures, and Observational QPO Counterparts
Orhan Donmez, M. Yousaf, Imtiaz Khan +1
We reveal the effect of the spacetime parameters on the accretion morphology formed through the BHL mechanism around a slowly rotating disformal Kerr black hole. Thus, we investiga…
