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,…
Model-independent cosmological inference after the DESI DR2 data with improved inverse distance ladder
Jia-Le Ling, Guo-Hong Du, Tian-Nuo Li +3
Recently, the baryon acoustic oscillations (BAO) measurements from the DESI survey have suggested hints of dynamical dark energy, challenging the standard CDM model. In this wo…
Impacts of dark energy on weighing neutrinos after DESI BAO
Guo-Hong Du, Peng-Ju Wu, Tian-Nuo Li +1
Recently, DESI has released baryon acoustic oscillation (BAO) data, and DES has also published its five-year supernova (SN) data. These observations, combined with cosmic microwave…
A search for sterile neutrinos in interacting dark energy models using DESI baryon acoustic oscillations and DES supernovae data
Lu Feng, Tian-Nuo Li, Guo-Hong Du +2
Sterile neutrinos can influence the evolution of the universe, and thus cosmological observations can be used to search for sterile neutrinos. In this study, we utilized the latest…
Prospects for measuring neutrino mass with 21-cm forest
Yue Shao, Guo-Hong Du, Tian-Nuo Li +1
Both particle physics experiments and cosmological observations have been used to explore neutrino properties. Cosmological researches of neutrinos often rely on the early-universe…
