Revisiting CPL with sign-switching density: To cross or not to cross the NECB
Mine Gökçen, Özgür Akarsu, Eleonora Di Valentino
Recent DESI DR2 BAO measurements, when combined with CMB and SNeIa data, exhibit a - preference for dynamical dark energy (DE) described by the CPL-parametrized equatio…
The Serendipitous Axiodilaton: A Self-Consistent Recombination-Era Solution to the Hubble Tension
Adam Smith, Maria Mylova, Carsten van de Bruck +2
Axio-dilaton cosmology provides a minimal benchmark model for both Dark Matter (DM) and Dark Energy (DE) that is well motivated by fundamental physics. The axion and dilaton arise…
Decay of quintessence into dark matter: mitigating the Hubble tension?
Giovanni Montani, Luis A. Escamilla, Nakia Carlevaro +1
We propose a revised cosmological scenario that extends the Cold Dark Matter (CDM) framework by incorporating metric gravity in the Jordan frame. In this model, the d…
III. Interacting Dark Energy: Summary of Models, Pathologies, and Constraints
Marcel van der Westhuizen, Amare Abebe, Eleonora Di Valentino
We present an overview of the main results from our two companion papers that are relevant for observational constraints on interacting dark energy (IDE) models. We provide analyti…
I. Linear Interacting Dark Energy: Analytical Solutions and Theoretical Pathologies
Marcel van der Westhuizen, Amare Abebe, Eleonora Di Valentino
Interacting dark energy (IDE) models, in which dark matter (DM) and dark energy (DE) exchange energy through a non-gravitational interaction, have long been proposed as candidates…
II. Non-Linear Interacting Dark Energy: Analytical Solutions and Theoretical Pathologies
Marcel van der Westhuizen, Amare Abebe, Eleonora Di Valentino
We investigate interacting dark energy (IDE) models with phenomenological, non-linear interaction kernels , specifically $Q_{1}=3Hδ\left(\frac{ρ_{\rm dm}ρ_{\rm de}}{ρ_{\rm dm}+ρ…
