Nonminimally coupled quintessence with sign-switching interaction
Jia-Qi Wang, Rong-Gen Cai, Zong-Kuan Guo +3
We propose a new nonminimally coupled quintessence model to account for the late-time dark energy dynamics indicated by recent Dark Energy Spectroscopic Instrument (DESI) measureme…
A Template-Based Search for Large-Scale-Structure--Correlated Anisotropy in the Nanohertz Gravitational-Wave Background Using the Public NANOGrav 15-Year Data Set
Yun Fang
Recent PTA analyses reporting evidence for a nanohertz common-spectrum process motivate targeted tests of whether any anisotropic component of the stochastic gravitational-wave bac…
Examining a new form of non-standard dark matter using DESI DR2 data
Yan-Hong Yao, Yi-Hao Shen, Tian-Nuo Li +2
In this work, we propose a non-standard dark matter (NSDM) model in which the equation of state (EoS) of dark matter (DM) is parameterized as , and this DM mo…
Model-independent late-universe measurements of and with the parametrization based on cosmic age-improved inverse distance ladder
Guo-Hong Du, Tian-Nuo Li, Jia-Le Ling +3
The standard model has encountered serious challenges and the tension has become more significant with increasingly precise cosmological observations. Meanwhile,…
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…
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…
Impact of particle production during inflation on the CMB detection
Xunliang Yang, Zhe Yu, Zhoujian Cao
This work focuses on particle production described by a nonminimally coupled model during inflation. In this model, three parameters determine the characteristic frequency and stre…
Anisotropies of cosmological gravitational wave backgrounds in non-flat spacetime
Rong-Gen Cai, Shao-Jiang Wang, Zi-Yan Yuwen +1
Recent reports of stochastic gravitational wave background from four independent pulsar-timing-array collaborations have renewed the interest in the cosmological gravitational wave…
Cosmic acceleration and the Hubble tension from baryon acoustic oscillation data
Xuchen Lu, Shengqing Gao, Yungui Gong
We investigate the null tests of cosmic accelerated expansion by using the Baryon Acoustic Oscillation (BAO) data measured by the Dark Energy Spectroscopic Instrument (DESI) and re…
