Constraining spinning primordial black holes with interstellar dust heating
Qianyong Li, Yupeng Yang
Primordial black holes (PBHs) are a well-motivated dark matter candidate, and their cosmic abundance is constrained by a variety of observational probes. PBHs in the mass range $10…
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 C…
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 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…
Muon neutrinos and the cosmological abundance of primordial black holes
Jiali Hao, Yupeng Yang, Qianyong Li +2
In the mixed dark matter scenarios consisting of primordial black holes (PBHs) and particle dark matter (DM), PBHs can accrete surrounding DM particles to form ultracompact minihal…
Signatures of the Self-organized Criticality Phenomenon in Precursors of Gamma-ray bursts
Xiu-Juan Li, Yu-Peng Yang
Precursors provide important clues to the nature of gamma-ray burst (GRB) central engines and can be used to contain GRB physical processes. In this letter, we study the self-organ…
The abundance of primordial black holes from the global 21cm signal and extragalactic gamma-ray background
Yupeng Yang
Primordial black holes (PBHs) formed in the early Universe can accret dark matter particles due to gravity and form ultracompact minihalos (UCMHs). The theoretical researches and s…
