Inflationary Models with Gauss-Bonnet Coupling in Light of ACT Observations
Yigan Zhu, Qing Gao, Yungui Gong +1
Recent analyses combining Atacama Cosmology Telescope (ACT) data with other cosmological datasets report a higher scalar spectral index , creating tension with a wide range of…
Observational constraints on inflationary models with non-minimally derivative coupling by ACT
Qing Gao, Yanjiang Qian, Yungui Gong +1
The most recent data release from the Atacama Cosmology Telescope (ACT) reveals a larger value of the scalar spectral tilt , ruling out a broad class of inflationary attractor…
Approximate reconstruction of inflationary potential with ACT observations
Zhu Yi, Xingzhi Wang, Qing Gao +1
The Atacama Cosmology Telescope (ACT) has recently reported updated measurements of the scalar spectral index , revealing a tension with the predictions of many conventional i…
Reconciling Nonminimally Coupled Higgs Inflation with ACT DR6 Observations through Reheating
Lang Liu, Zhu Yi, Yungui Gong
The Higgs inflation model with nonminimal coupling, while disfavored by the 1 region of the latest Atacama Cosmology Telescope Data Release 6 (ACT DR6) observational data, can b…
Non-minimal coupling in light of ACT
Qing Gao, Yungui Gong, Zhu Yi +1
The latest ACT data release disfavors the attractor . In inflationary models with nonminimal coupling, such attractors typically arise in the strong coupling limit. To a…
Constant-roll inflation with non-minimally derivative coupling
Jie Liu, Yungui Gong, Zhu Yi
We investigate the constant-roll inflation with non-minimally kinetic coupling to the Einstein tensor. With the slow-roll parameter being a constant, we cal…
