Exploring non-cold dark matter in a scenario of dynamical dark energy with DESI DR2 data
Tian-Nuo Li, Peng-Ju Wu, Guo-Hong Du +3
Recent observations of DESI hint that dark matter (DM) may not be cold but have a non-zero equation of state (EoS) parameter, and that dark energy (DE) may not be a cosmological co…
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…
Testing the cosmic distance duality relation with baryon acoustic oscillations and supernovae data
Tian-Nuo Li, Guo-Hong Du, Peng-Ju Wu +3
One of the most fundamental relationships in modern cosmology is the cosmic distance duality relation (CDDR), which describes the relationship between the angular diameter distance…
Revisiting the phenomenologically emergent dark energy model: is non-zero equation of state of dark matter favored by DESI DR2?
Tian-Nuo Li, Yi-Min Zhang, Yan-Hong Yao +3
The nature of dark matter remains one of the most fundamental and unresolved questions in modern cosmology. In most cosmological models, dark matter is typically modeled as pressur…
Comparison of dark energy models using late-universe observations
Peng-Ju Wu
In the framework of general relativity, dark energy was proposed to explain the cosmic acceleration. A pivotal inquiry in cosmology is to determine whether dark energy is the cosmo…
Cosmological search for sterile neutrinos after DESI 2024
Guo-Hong Du, Tian-Nuo Li, Peng-Ju Wu +4
The question of whether the massive sterile neutrinos exist remains a crucial unresolved issue in both particle physics and cosmology. We explore the cosmological constraints on th…
Probing the sign-changeable interaction between dark energy and dark matter with DESI baryon acoustic oscillations and DES supernovae data
Tian-Nuo Li, Guo-Hong Du, Yun-He Li +4
There is a possibility of interaction between dark energy and dark matter, and this interaction may also undergo a sign change during the evolution of the universe. In this paper,…
