If sub-GeV Dark matter(DM) annihilates to the charged particles such as , , or , it generates an additional source of electrons and positrons in the cosm…
Constraining primordial black holes as dark matter using AMS-02 data
Bing-Yu Su, Xu Pan, Guan-Sen Wang +3
Primordial black holes (PBHs) are the plausible candidates for the cosmological dark matter. Theoretically, PBHs with masses in the range of $4\times10^{14}\sim 10^{1…
Weak Lensing Constraints on Dark Matter-Baryon Interactions with -Body Simulations and Machine Learning

Guan-Sen Wang, Zhan-Fang Chen, Lei Zu +3
Omega Centauri, the largest known globular cluster in the Milky Way, is believed to be the remains of a dwarf galaxy's core. Giving its potential abundance of dark matter (DM), it…
Multi-frequency test of dark matter annihilation into long-lived particles in Sirius
Yu-Xuan Chen, Lei Zu, Zi-Qing Xia +2
New long-lived particles produced at the colliders may escape from conventional particle detectors. Using satellites or ground telescopes, we can detect the photons generated from…
The Possibility of Mirror Planet as Planet Nine in Solar System
Pei Wang, Yu Chen Tang, Lei Zu +2
A series of dynamical anomalies in the orbits of distant trans-Neptunian objects points to a new celestial body (usually named Planet Nine) in the solar system. In this draft, we p…
