Neutrino mass constraints in interacting dark energy models after DESI DR2
Hui Li, Guo-Hong Du, Tian-Nuo Li +4
Recent DESI observations indicate a deviation from the CDM model, showing a preference for dynamical dark energy and thereby relaxing the upper limit on the neutrino mass withi…
Measuring neutrino mass in light of ACT DR6 and DESI DR2
Lu Feng, Tian-Nuo Li, Guo-Hong Du +2
The recent release of high-precision cosmological data, particularly the small-scale cosmic microwave background (CMB) measurements from ACT and baryon acoustic oscillation (BAO) d…
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…
Revisiting holographic dark energy after DESI 2024
Tian-Nuo Li, Yun-He Li, Guo-Hong Du +4
New insights from the Dark Energy Spectroscopic Instrument (DESI) 2024 baryon acoustic oscillations (BAO) data, in conjunction with cosmic microwave background (CMB) and Type Ia su…
Nanohertz gravitational waves from a quasar-based supermassive black hole binary population model as dark sirens
Si-Ren Xiao, Yue Shao, Ling-Feng Wang +4
Recently, several pulsar timing array (PTA) projects have detected evidence of the existence of a stochastic gravitational wave background (SGWB) in the nanohertz frequency band, p…
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…
