Reconstructing sign-switching dark energy histories: Scalar-field regularity, conditional potential comparison, and representative dynamics
Shahnawaz A. Adil, Özgür Akarsu, Mariam Bouhmadi-López +3
Phenomenologically similar sign-switching dark-energy histories need not have comparable scalar-field realizations. We reconstruct minimally coupled scalars with fixed kinetic sign…
Modified Teleparallel Gravity, DESI BAO and the Tension
Mariam Bouhmadi-López, Carlos G. Boiza, Maria Petronikolou +1
We investigate whether late-time modifications of gravity in the teleparallel framework can impact the current tension in the Hubble constant , focusing on cosmology as…
Cosmological perturbations for smooth sign-switching dark energy models
Mariam Bouhmadi-López, Beñat Ibarra-Uriondo
In this work, we carry out a comprehensive perturbative analysis of four cosmological models featuring a sign-switching cosmological constant. Among these, we include the well-know…
