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…
Statistical Properties of X-Ray Bursts from SGR J1935+2154 Detected by Insight-HXMT
Wen-Long Zhang, Xiu-Juan Li, Yu-Peng Yang +5
As one class of the most important objects in the universe, magnetars can produce a lot of different frequency bursts including X-ray bursts. In \cite{2022ApJS..260...24C}, 75 X-ra…
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…
Constraints on primordial black holes in the mixed dark matter scenarios using the ratio
Yupeng Yang, Xiujuan Li, Gang Li
We derive the upper limit on the dark matter (DM) fraction in primordial black holes (PBHs) in the mixed DM scenarios. In this scenarios, a PBH can accrete weakly interacting massi…
Influence of the deviation of the matter power spectrum at small scales on the global 21-cm signal at cosmic dawn
Yupeng Yang, Xiujuan Li, Gang Li
The matter power spectrum has been strongly constrained by astronomical measurements at large scales, but only weakly at small scales. Compared with the standard scenario, the devi…
Evidence for self-organized criticality phenomena in prompt phase of short gamma-ray bursts
Xiu-Juan Li, Wen-Long Zhang, Shuang-Xi Yi +2
The prompt phase of gamma-ray burst (GRB) contains essential information regarding the physical nature and central engine, which are as yet unknown. In this paper, we investigate t…
An analytic derivation of the empirical correlations of gamma-ray bursts
Fan Xu, Yong-Feng Huang, Jin-Jun Geng +3
Empirical correlations between various key parameters have been extensively explored ever since the discovery of gamma-ray bursts (GRBs) and have been widely used as standard candl…
