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 finding…
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…
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…
