Assessing the consistency of the CPL dark-energy model with cosmological data: Simulation-calibrated neural posterior disagreement
Tian-Yang Sun, Tian-Nuo Li, Guo-Hong Du +3
Recent DESI observations hint at a preference for dynamical dark energy with an equation of state that crosses the phantom divide within the Chevallier-Polarski-Linder (CPL) parame…
Conditional variational autoencoders for cosmological model discrimination and anomaly detection in cosmic microwave background power spectra
Tian-Yang Sun, Tian-Nuo Li, He Wang +2
The cosmic microwave background power spectra are a primary window into the early universe. However, achieving interpretable compression and fast inference diagnostics under weak m…
Gravitational wave standard sirens: A brief review of cosmological parameter estimation
Shang-Jie Jin, Ji-Yu Song, Tian-Yang Sun +5
Gravitational wave (GW) observations are expected to serve as a powerful and independent probe of the expansion history of the universe. By providing direct and calibration-free me…
Deep learning-driven likelihood-free parameter inference for 21-cm forest observations
Tian-Yang Sun, Yue Shao, Yichao Li +3
The hyperfine structure absorption lines of neutral hydrogen in spectra of high-redshift radio sources, known collectively as the 21-cm forest, have been demonstrated as a sensitiv…
