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…
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,…
A cosmological model with time dependent , and viscous fluid in General Relativity
Rishi Kumar Tiwari, Alnadhief H. A. Alfedeel, Değer Sofuoğlu +2
In this paper, we investigate Bianchi type cosmological models with bulk viscous fluid and time varying cosmological and Newtonian parameters. The Einstein's field equa…
