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…
A Review on Resolving the Hubble Tension via Late-Universe Physics
Xuan-Dong Jia, Xin-Yi Dai, Yu-Peng Yang +1
The CDM cosmological model has been successful in explaining many astronomical observations. However, recent observations increasingly point to deviations from the standard $Î…
Spectral Hardness as the Primary Discriminator: Unveiling the Collapsar--Merger Boundary with a Gold-Standard Gamma-Ray Burst Sample
Xue Zhang, Yan-Kun Qu, Shuang-Xi Yi +4
In this Letter, we establish a robust, physically motivated classification method using a Support Vector Machine (SVM) trained on a "gold-standard" sample of 24 GRBs with spectrosc…
Constraining deviations from CDM in the Hubble expansion rate
Yupeng Yang
The CDM cosmolgical model has long been regarded as highly successful in accurately describing a wide range of astronomical observations. However, numerous observational findin…
Cosmological abundance of primordial black holes in mixed dark matter scenarios incorporating Kaluza-Klein dark matter
Yupeng Yang, Qianyong Li, Jiali Hao +1
The lightest Kaluza-Klein (KK) dark matter particles and primordial black holes (PBHs) emerge as plausible candidates for dark matter. In scenarios where dark matter is a mix of KK…
The redshift evolution of the luminosity function of type II GRBs
Yan-Kun Qu, Zhong-Xiao Man, Yu-Peng Yang +3
As of December 2023, the Swift satellite has detected more than 1600 gamma-ray bursts (GRBs). We select 307 Type II GRBs for constructing the luminosity function (LF) based on the…
