Constraints on ultra-slow-roll inflation with the NANOGrav 15-Year Dataset
Bo Mu, Jing Liu, Gong Cheng +1
Ultra-slow-roll~(USR) inflation predicts an exponential amplification of scalar perturbations at small scales, which leads to a stochastic gravitational wave background~(SGWB) thro…
Constraints on ultra-slow-roll inflation from the third LIGO-Virgo observing run
Bo Mu, Gong Cheng, Jing Liu +1
The nonattractor evolution in ultra-slow-roll (USR) inflation results in the amplification of superhorizon curvature perturbations and then induces a strong and detectable stochast…
Cosmological test of an extended quintessence model
Gong Cheng, Fengquan Wu, Xuelei Chen
We investigate the cosmological observational test of the extended quintessence model, i.e. a scalar-tensor gravity model with a scalar field potential serving as dark energy, by u…
Cosmological constraints on ultra-light axion fields
Jiangang Kang, Yan Gong, Gong Cheng +1
Ultra-light axions (ULAs) with mass less than 10^-20 eV have interesting behaviors that may contribute to either dark energy or dark matter at different epochs of the Universe. Its…
Cross-Correlation of Far-Infrared Background Anisotropies and CMB Lensing from Herschel and Planck satellites
Ye Cao, Yan Gong, Chang Feng +3
The cosmic infrared background (CIB) anisotropies and cosmic microwave background (CMB) lensing are powerful measurements for exploring the cosmological and astrophysical problems.…
Testing interacting dark matter and dark energy model with cosmological data
Gong Cheng, Yin-Zhe Ma, Fengquan Wu +2
We investigate the model of dark matter-dark energy (DM-DE) interaction with coupling strength proportional to the multiplication of dark sector densities with different power indi…
Features and stability analysis of non-Schwarzschild black hole in quadratic gravity
Yi-Fu Cai, Hezi Zhang, Junyu Liu +2
Black holes are found to exist in gravitational theories with the presence of quadratic curvature terms and behave differently from the Schwarzschild solution. We present an exhaus…
