Do DESI-DR2 BAO data imply a coupling of dark matter and dark energy?
Weiqiang Yang, Sibo Zhang, Dinorah Barbosa +3
We revisit an interacting dark matter (DM) -- dark energy (DE) model characterized by the interaction function , where is a constant coupling parameter and is t…
A Periodically Interacting Dark Sector: Signatures and Constraints from CMB and Cosmic Expansion Data
Marco Antonio Cardoso Alvarez, Micol Benetti, Leila Graef +1
We introduce a novel cosmological model that provides an effective description of the back-reaction of super-Hubble fluctuations on the cosmological background, a generic effect ex…
Genericness of quantum damping of cosmological shear in modified loop quantum cosmology
Wen-Cong Gan, Leila L. Graef, Rudnei O. Ramos +2
In arXiv:2603.18175, the authors argue, based on numerical studies of particular cases, that the quantum damping of cosmological shear in a modified loop quantum cosmological model…
Sound Speed Resonance in the Gravitational Wave Background as a probe for non-standard early universe cosmologies
Igor de O. C. Pedreira, Amara Ilyas, Ziwei Wang +2
Gravitational waves constitute a powerful probe of the underlying theory of gravity. In extensions of general relativity, additional degrees of freedom, such as scalar fields in th…
