Null tests with Gaussian Process
Shengqing Gao, Qing Gao, Yungui Gong +1
We investigate the null tests of spatial flatness and the flat CDM model using the Baryon Acoustic Oscillation (BAO) data measured by the Dark Energy Spectroscopic Instrument (D…
On the evidence of dynamical dark energy
Qing Gao, Zhiqian Peng, Shengqing Gao +1
To elucidate the robustness of the baryon acoustic oscillation (BAO) data measured by the Dark Energy Spectroscopic Instrument (DESI) in capturing the dynamical behavior of dark en…
On the duality in constant-roll inflation
Yue Wang, Qing Gao, Shengqing Gao +1
There is a duality in the observables , and the inflaton potential between large and small for the constant-roll inflation if the slow-roll parameter is neglig…
Primordial black holes and scalar-induced gravitational waves from the polynomial attractor model
Zhongkai Wang, Shengqing Gao, Yungui Gong +1
Primordial black holes (PBHs) generated in the early Universe are considered as one of the candidates for dark matter. To produce PBHs with sufficient abundance, the primordial sca…
Primordial black holes and scalar induced gravitational waves from Higgs inflation with non-canonical kinetic term
Jiong Lin, Shengqing Gao, Yungui Gong +3
We resolve the potential-restriction problem in K/G inflation by introducing nonminimal coupling. In this context, Higgs field successfully drives inflation satisfying CMB observat…
