A Class of Exact Single-Field Inflationary Solutions beyond Slow Roll
Jia-Wei Zhang, Bai-Cian Ke, Yao Yu +2
We construct exact solutions for single-field inflaton dynamics without invoking the slow-roll approximation. A suitable change of variables reduces the background equation to an A…
Constraints on interacting dark energy models from time-delay cosmography with seven lensed quasars
Ling-Feng Wang, Jie-Hao Zhang, Dong-Ze He +2
Measurements of time-delay cosmography of lensed quasars can provide an independent probe to explore the expansion history of the late-time Universe. In this paper, we employ the t…
Forecast for cosmological parameter estimation with gravitational-wave standard siren observation from the Cosmic Explorer
Shang-Jie Jin, Dong-Ze He, Yidong Xu +2
The third-generation ground-based gravitational-wave (GW) detector, Cosmic Explorer (CE), is scheduled to start its observation in the 2030s. In this paper, we make a forecast for…
Expected LHAASO sensitivity to decaying dark matter signatures from dwarf galaxies gamma-ray emission
Dong-Ze He, Xiao-Jun Bi, Su-Jie Lin +2
As a next-generation complex extensive air shower array with a large field of view, the large high altitude air shower observatory (LHAASO) is very sensitive to the very high energ…
Constraints on active and sterile neutrinos in an interacting dark energy cosmology
Lu Feng, Dong-Ze He, Hai-Li Li +2
We investigate the impacts of dark energy on constraining massive (active/sterile) neutrinos in interacting dark energy (IDE) models by using the current observations. We employ tw…

Ming-Ming Zhao, Rui-Yun Guo, Dong-Ze He +2
In this paper, we make a comparison for the impacts of smooth dynamical dark energy, modified gravity, and interacting dark energy on the cosmological constraints on the total mass…
Probing the sign-changeable interaction between dark energy and dark matter with current observations
Juan-Juan Guo, Jing-Fei Zhang, Yun-He Li +2
We consider the models of vacuum energy interacting with cold dark matter in this study, in which the coupling can change sigh during the cosmological evolution. We parameterize th…
