Radio Plateaus in Gamma-Ray Burst Afterglows and Their Application in Cosmology

Xiao Tian, Jia-Lun Li, Shuang-Xi Yi +4

The plateau phase in the radio afterglows has been observed in very few gamma-ray bursts (GRBs), and 27 radio light curves with plateau phase were acquired from the published liter…

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…

Contributions of dark matter annihilation within ultracompact minihalos to the 21cm background signal

Yupeng Yang

In the dark age of the universe, any exotic sources, e.g. the dark matter annihilation, which inject the energy into the intergalactic medium (IGM) will left some imprint on the 21…

Constraints on the ultracompact minihalos using neutrino signals from the gravitino dark matter decay

Yun-Long Zheng, Yu-Peng Yang, Ming-Zhe Li +1

Ultracompact dark matter minihalos (UCMHs) would be formed during the earlier universe if there were large density perturbations. If the dark matter can decay into the standard mod…
