Holographic dark energy as a source for slowly rotating wormholes: Implications for null geodesics and shadows
A. Errehymy, S. K. Maurya, M. Govender +4
In this work, we explore for the first time slowly rotating traversable wormholes embedded in holographic dark energy. We focus on three representative holographic dark energy mode…
Probing geometrically perturbed strange stars with minimal decoupling using millisecond pulsar timing observations
K. N. Singh, S. K. Maurya, A. Errehymy +3
We construct a gravitationally decoupled anisotropic strange star model using the minimal geometric deformation approach with a MIT bag equation of state and an additional source s…
Scalar-Wave Signatures of Wormholes in Dark Matter Halos
Abdullah Guvendi, Omar Mustafa, Semra Gurtas Dogan +2
We identify scalar-wave signatures of massless fields propagating in static, spherically symmetric wormholes embedded within realistic dark matter halos. Starting from a general li…
Null geodesics and shadows of slowly rotating wormholes immersed in dark matter halos
Abdelghani Errehymy, Abdullah Guvendi, Semra Gurtas Dogan +1
We study slowly rotating traversable wormholes embedded in realistic galactic dark matter halos, including Navarro-Frenk-White (NFW), Bose-Einstein Condensate (Thomas-Fermi, TF), a…
Relativistic massive compact stars supported by decoupled matter: Implications for mass-radius bounds
S. K. Maurya, A. Errehymy, Ksh. Newton Singh +2
The merger of binary neutron stars (BNSs) is a remarkable astrophysical event where all four fundamental forces interplay dynamically across multiple stages, producing a rich spect…
Role of gravitational decoupling on theoretical insights of relativistic massive compact stars in the mass gap
S. K. Maurya, A. Errehymy, Ksh. Newton Singh +2
Advancements in theoretical simulations of mass gap objects, particularly those resulting from neutron star mergers and massive pulsars, play a crucial role in addressing the chall…
