Chaotic Imprints in Gravitational Waves from Extreme-Mass-Ratio-Inspirals Embedded in Dark Matter Halo
Surajit Das, Surojit Dalui, Bum-Hoon Lee +1
We investigate imprints of chaos in gravitational waves from extreme-mass-ratio inspirals configuration, where a stellar massive object, confined in an external potential as a harm…

Extreme-Mass-Ratio Inspirals Embedded in Dark Matter Halo: Existence of Homoclinic Orbit and Horizon-Induced Chaos
Surajit Das, Surojit Dalui, Bum-Hoon Lee +1
We study the existence of homoclinic orbit and the onset of chaotic motion for a massive particle moving around a Schwarzschild-like black hole embedded in a Dehnen-(1,4,5/2) type…

Black holes immersed in modified Chaplygin-like dark fluid and cloud of strings: geodesics, shadows, and images
Xiang-Qian Li, Yoonbai Kim, Bum-Hoon Lee +2
This study investigates a black hole surrounded by a cloud of strings and a cosmological dark fluid characterized by a modified Chaplygin-like equation of state (MCDF), $p=Aρ-B/ρ^β…
