Refining primordial black hole dark matter constraints with dust heating: the role of spin and halo profile dependence
Shaobin Hu, Yupeng Yang, Chengjie Sun +5
The paper studies how spinning primordial black holes heat interstellar dust via Hawking radiation and derives constraints on their dark‑matter fraction, examining how these limits…
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…
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 $Ï_{m}\propto(1+z)^{3-\v…
