Constraining primordial black holes in dark matter with kinematics of dwarf galaxies
Bo-Qiang Lu, Yue-Liang Wu
We propose that the kinematical observations of dwarf galaxies can be used to constrain the primordial black hole's (PBH) abundance in dark matter since the presence of primordial…
Damping of gravitational waves in a viscous Universe and its implication for dark matter self-interactions
Bo-Qiang Lu, Da Huang, Yue-Liang Wu +1
It is well known that a gravitational wave (GW) experiences the damping effect when it propagates in a fluid with nonzero shear viscosity. In this paper, we propose a new method to…
Constraints on the Sommerfeld-enhanced dark matter annihilation from the gamma rays of subhalos and dwarf galaxies
Bo-Qiang Lu, Yue-Liang Wu, Wei-Hong Zhang +1
The substructures of the Galactic dark matter halo such as dark matter subhalos and dwarf galaxies have very low velocity dispersions, which makes them useful in constraining the s…
Limits on the Dark Matter from AMS-02 antiproton and positron fraction data
Bo-Qiang Lu, Hong-Shi Zong
We derive limits on the dark matter annihilation cross section and lifetime using measurements of the AMS-02 antiproton ratio and positron fraction data. In deriving the limits, we…
The `excess' of primary cosmic ray electrons
Xiang Li, Zhao-Qiang Shen, Bo-Qiang Lu +5
With the accurate cosmic ray (CR) electron and positron spectra (denoted as and , respectively) measured by AMS-02 collaboration, the difference betw…
