Dark Energy in the DESI Era: A Brief Review of Evidence, Beyond-CDM Interpretations, and Tensions
Tian-Nuo Li, Guo-Hong Du, Hao Wang +3
The paper reviews recent DESI BAO measurements that hint at dynamical dark energy and examines various beyond‑ΛCDM scenarios and their implications for cosmological tensions like t…
Robust Preference for Dark Sector Interactions
Tian-Nuo Li, William Giarè, Guo-Hong Du +4
The paper investigates whether interactions between dark matter and dark energy can explain recent DESI BAO observations, finding strong statistical evidence for such interactions…
Model-independent late-universe measurements of and with the parametrization based on cosmic age-improved inverse distance ladder
Guo-Hong Du, Tian-Nuo Li, Jia-Le Ling +3
The standard model has encountered serious challenges and the tension has become more significant with increasingly precise cosmological observations. Meanwhile,…
Neutrino mass constraints in the Schwarzschild-de Sitter black-hole dark energy model with ACT DR6 and DESI DR2 data
Sheng-Han Zhou, Tian-Nuo Li, Guo-Hong Du +4
Recent DESI observations have posed new challenges to CDM, showing a preference for dynamical dark energy and yielding neutrino mass constraints within CDM that approach th…
Cosmological preference for a positive neutrino mass at 2.7: A joint analysis of DESI DR2, DESY5, and DESY1 data
Guo-Hong Du, Tian-Nuo Li, Peng-Ju Wu +2
Neutrinos and dark energy (DE) have entered a new era of investigation, as the latest DESI baryon acoustic oscillation measurements tighten the constraints on the neutrino mass and…
Alleviating the tension through the interacting dark energy model from quantum gravitational field theory in light of DESI DR2
Yi-Min Zhang, Tian-Nuo Li, Guo-Hong Du +4
Recent DESI DR2 data has shown a significant preference for dynamical dark energy, yet this has further exacerbated the tension. In this work, we explore the potential of int…
