Constraining primordial black holes and primordial curvature power spectrum with extragalactic muon neutrino
Yupeng Yang
We investigate a mixed dark matter scenario comprising weakly interacting massive particles (WIMPs) and primordial black holes (PBHs). After PBH formation, WIMPs can accrete onto t…
Constraints on redshift-evolving Hubble constant models with early- and late-time diagnostics
Yupeng Yang
We systematically investigate four cosmological models within a parameterized framework that allows for a redshift dependence of \(H_0\): three phenomenological models (\(αΛ\)CDM,…
Galactic constraints on spinning primordial black hole dark matter from interstellar dust heating
Shaobin Hu, Yupeng Yang, Chengjie Sun +5
Primordial black holes (PBHs) are compelling dark matter candidates. PBHs with masses between and can heat interstellar dust via Hawking radiation.…
Redshift evolution of the Hubble constant: Constraints and new insights from an interacting dark energy model
Xinyi Dai, Yupeng Yang, Yicheng Wang +3
We develop a modified interacting dark energy (IDE) model to study the redshift evolution of the Hubble constant (), in light of the Hubble tension. In this framework, the ene…
New cosmological constraints on the evolution of dark matter energy density
Yupeng Yang, Xinyi Dai, Yicheng Wang
We constrain the evolution of dark matter energy density over time, specifically focusing on deviation from the standard model represented by the equation $ρ_{m}\propto(1+z)^{3-\va…
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…
Constraints on primordial black holes with CMB spectral distortions
Yupeng Yang
In the mixed dark matter scenarios consisting of primordial black holes (PBHs) and weakly interacting massive particles (WIMPs), WIMPs can be accreted onto PBHs to form ultracompac…
Contributions of dark matter annihilation to the global 21cm spectrum observed by the EDGES experiment
Yupeng Yang
The EDGES experiment has observed an absorption feature in the global 21 cm spectrum with a surprisingly large amplitude. These results can be explained by decreasing the kinetic t…
Tau neutrinos from ultracompact dark matter minihalos and constraints on the primordial curvature perturbations
Yupeng Yang, Yan Qin
The observations and research on the neutrinos provide a kind of indirect way of revealing the properties of dark matter particles. For the detection of muon neutrinos, the main is…
Constraints on the basic parameters of dark matter using the Planck data
Yupeng Yang
Dark Matter annihilation or decay can affect the anisotropy of the cosmic microwave background (CMB). Therefore, the CMB data can be used to constrain the properties of a dark matt…
Constraints on the primordial power spectrum of small scales using the neutrino signals from the dark matter decay
Yupeng Yang
Many inflation theories predict that the primordial power spectrum is scale invariant. The amplitude of the power spectrum can be constrained by different observations such as the…
Neutrino signals from ultracompact minihalos and constraints on the primordial curvature perturbation
Yupeng Yang, Guilin Yang, Hongshi Zong
Compared with that of standard dark matter halos, the density profile of the recently proposed new kind of dark matter structure named ultracompact minihalos (UCMHs) is steeper and…
The contribution of ultracompact dark matter minihalos to the isotropic radio background
Yupeng Yang, Guilin Yang, Xiaoyuan Huang +3
The ultracompact minihalos could be formed during the earlier epoch of the universe. The dark matter annihilation within them is very strong due to the steep density profile, $ρ\si…
Constraints on ultracompact minihalos from extragalactic γ-ray background
Yupeng Yang, Lei Feng, Xiaoyuan Huang +3
It has been proposed that ultracompact minihalos (UCMHs) might be formed in earlier epoch. If dark matter consists of Weakly Interacting Massive Particles (WIMPs), UCMHs can be tre…
The Abundance of New Kind of Dark Matter Structures
Yupeng Yang, Xuelei Chen, Tan Lu +1
A new kind of dark matter structures, ultracompact minihalos (UCMHs) was proposed recently. They would be formed during the radiation dominated epoch if the large density perturbat…
