Cosmological Constraints on the DGP Model in light of DESI DR2 2025 Data
Xinyi Dai, Yupeng Yang, Yicheng Wang
We present updated constraints on both flat and non-flat Dvali-Gabadadze-Porrati (DGP) cosmological models using the latest baryon acoustic oscillation (BAO) measurements from the…
Cosmological constraints on the big bang quantum cosmology model
Yicheng Wang, Yupeng Yang, Xinyi Dai +3
The big bang quantum cosmology model introduces the trace of the Schouten tensor as a form of dynamic dark energy. Together with cold dark matter, these components form the so-…
Redshift evolution of the Hubble constant: Constraints and new insights from an interacting dark energy model
Xinyi Dai, Yupeng Yang, Yicheng Wang +3
We develop a modified interacting dark energy (IDE) model to study the redshift evolution of the Hubble constant (), in light of the Hubble tension. In this framework, the ene…
Optimization of Laser Irradiation Uniformity for the Double-Cone Ignition Scheme with MULTI-3D simulations
Yicheng Wang, Yiwen Yang, Fuyuan Wu +3
The double-cone ignition (DCI) scheme holds a promising perspective for laser driven fusion energy and astrophysics. However, optimizing the laser irradiation uniformity under the…
New cosmological constraints on the evolution of dark matter energy density
Yupeng Yang, Xinyi Dai, Yicheng Wang
We constrain the evolution of dark matter energy density over time, specifically focusing on deviation from the standard model represented by the equation $Ï_{m}\propto(1+z)^{3-\v…
Cosmological constraints on two vacuum decay models
Yupeng Yang, Yicheng Wang, Xinyi Dai
We constrain two vacuum decay models (CDM, proposed by the authors of~\cite{Brito:2024bhh}) utilizing the baryon acoustic oscillations (BAO) data released by the Dark Energy…
