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-…
Charged particle bound orbits around magnetized Schwarzschild black holes: S2 star and hotspot applications
Uktamjon Uktamov, Mohsen Fathi, Javlon Rayimbaev
The dynamics of charged particles around magnetized black holes provide valuable insights into astrophysical processes near compact objects. In this work, we investigate the bound…
Cosmological evolution driven by polytropic fluids in an inhomogeneous spacetime
Gilberto Aguilar-Pérez, Miguel Cruz, Mohsen Fathi +2
Addressing the late-time accelerated expansion of the universe, known as the "dark energy problem", remains a central challenge in cosmology. While the cosmological constant is the…
Shadows aspect of rotating black holes in the Einstein-AdS SU(N)-nonlinear sigma model
Mohsen Fathi, Yassine Sekhmani
Recent observations of the supermassive black holes M87* and Sgr A* by the Event Horizon Telescope (EHT) have opened new avenues for testing gravity theories through black hole sha…
Shedding Light on Gravity: Black Hole Shadows and Lensing Signatures in Lorentz Gauge Theory
Ali Övgün, Mohsen Fathi
Recent advances, including gravitational wave detections and imaging of black hole shadows, have strongly validated general relativity. Nevertheless, ongoing cosmological observati…
Effect of primary scalar hair on black hole's strong lensing in Beyond Horndeski Gravity
Mohsen Fathi
We study the gravitational lensing effects of a static, asymptotically flat black hole with primary scalar hair in Beyond Horndeski gravity, focusing on the strong lensing regime.…
