Testing Charged Black Holes Embedded in Anisotropic Matter and Surrounded by Plasma through Gravitational Lensing: Bounds from the Sloan Lens ACS Survey
Ritesh Pandey, Shubham Kala, Amare Abebe +2
We investigate weak gravitational lensing by a charged black hole surrounded by anisotropic matter, described by the two-component Kiselev metric, and immersed in a homogeneous pla…
Constraint closure and gravitational-wave content of shear-free cosmologies in metric f(R) gravity
Mudhahir Al Ajmi, Amare Abebe
We derive the consistency conditions governing the propagating content of linear shear-free perturbations of Friedmann-Lema\^ıtre-Robertson-Walker cosmologies in metric grav…
A No-Go Theorem for Curvature Neutrality in f(Q) Cosmology?
Gamal G. L. Nashed, Amare Abebe
In the framework of gravity, we investigate whether spatial curvature can be made dynamically invisible in the cosmological background equations. We consider open spatial se…
Effective Constrained Scalar--Gauss--Bonnet Inflation Motivated by Gravity
G. G. L. Nashed, Sudan Hansraj, Amare Abebe
We develop an effective framework for inflation in a constrained scalar--Gauss--Bonnet theory motivated by a restricted sector of gravity. Using unified parametr…
Rotating traversable wormholes and particle dynamics in gravity
G. G. L. Nashed, Waleed El Hanafy, Amare Abebe +2
Traversable wormholes are among the most interesting solutions of gravitational theories, but within General Relativity they generally require exotic matter violating the null ener…
Alleviating the Hubble Tension Using Coupled Dark Energy - Dark Matter Interaction
Yismaw Wassie Ambelu, Amare Abebe, Solomon Belay Tessema +1
We investigate two interacting dark energy models, CDM and CDM, as potential means of alleviating the tension, using DESI DR2 BAO data along with the Planck 2018 CMB,…
