Late-Time Emergence of Dark Energy and Its Interaction with Dark Matter
Sibo Zhang, Weiqiang Yang, Supriya Pan +3
We present an interacting scenario between dark energy (DE) and dark matter (DM), where DE has an emergent nature, that means, DE was absent in the early universe but it becomes ef…
Testing Matter Diffusion with Late-Time Cosmological Observations
Alireza Zafari, Mohammad-Hossein Namdar, Luis A. Escamilla +1
We investigate a class of late-time cosmological models derived from the phenomenological framework of variable matter diffusion. In these scenarios, energy-momentum conservation r…
Intertwined Constraints in Extended Cosmologies: Dark Energy, Curvature, Neutrinos, and Inflation
William Giarè, Dong Ha Lee, Eleonora Di Valentino
We present a systematic reassessment of cosmological constraints beyond CDM by progressively relaxing the assumptions underlying Dark Energy (DE), Curvature, Neutrinos, and Infl…
General Relativistic Entropic Acceleration at the perturbation level: a CLASS implementation and first Boltzmann-code constraints
Simone D'Onofrio, Dong Ha Lee, Eleonora Di Valentino +1
General Relativistic Entropic Acceleration (GREA) attributes the late-time acceleration of the Universe to the entropy growth of the causal cosmological horizon, without a cosmolog…
Evolving Dark Energy Is Vacuum Energy After All
Dong Ha Lee, Carsten van de Bruck, Eleonora Di Valentino +2
We investigate a physically motivated model of dynamical dark energy arising from the non-perturbative topological structure of the Quantum Chromodynamics (QCD) vacuum. The model i…
Model-Independent Indication for a Localized Anomaly in the Late-Time Expansion History
Shibendu Gupta Choudhury, Purba Mukherjee, Eleonora Di Valentino +1
We investigate the late-time expansion history of the Universe using a model-independent spline reconstruction of cosmological distances based on the latest DESI DR2 baryon acousti…
