Dark matter imprints on a caustic encounter in an effective spinning black hole binary lens
Mohsen Fathi
We ask whether a cored dark matter (DM) correction can leave a resolved caustic trace after a spinning vacuum binary is allowed to imitate it. The vacuum comparison varies lens sca…
Dark matter environments and safeguards for spacetime inference from horizon scale interferometry
Mohsen Fathi
The paper investigates how dark‑matter distributions and extra‑dimensional tidal charges around rotating black holes affect horizon‑scale observables such as shadows and photon reg…
Adaptive ray tracing, image diagnostics, and photon ring signatures of rotating dark-matter-dressed black holes
Mohsen Fathi
We study the optical appearance of rotating black holes embedded in dark matter environments using a phenomenological ray tracing framework. Rather than focusing on a single geomet…
A dark-matter-sensitive orientation clock near rotating black holes
Mohsen Fathi
A coherent triaxial structure has an intrinsic orientation clock because rotation about its intermediate principal axis is unstable. I ask how this clock changes when the structure…
Strong-lensing degeneracies of black holes embedded in self-interacting scalar field dark matter halos
Mohsen Fathi, Gabriel Gómez
In this paper, we explore the strong gravitational lensing properties of black holes embedded in self-interacting scalar field dark matter halos, together with NFW-type configurati…
Interacting Generalized Chaplygin-Jacobi gas: Thermodynamics approach
Gilberto Aguilar-Pérez, Miguel Cruz, Mohsen Fathi +1
This work investigates a cosmological model featuring an interaction between dark energy and dark matter, where the dark energy component is described by the Generalized Chaplygin-…
