Prospects for cosmological research using hundred-meter-class radio telescopes: 21-cm intensity mapping survey strategies with QTT, JRT, and HRT
Jun-Da Pan, Yichao Li, Guo-Hong Du +2
Understanding dark energy requires precision measurements of the expansion history of the universe and the growth of large-scale structure. The 21 cm intensity mapping (21 cm IM) t…
Measuring neutrino masses with joint JWST and DESI DR2 data
Sheng-Han Zhou, Tian-Nuo Li, Guo-Hong Du +3
Early JWST observations reveal an unexpectedly abundant population of high-redshift candidate massive galaxies at , and recent DESI measurements show a preference for…
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…
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…
