Challenges in Binary Pulsar Timing Detection of Dark Matter Subhalos
Zheng-Long Wang, Zi-Qing Xia, Yue-Lin Sming Tsai +1
Recently, binary pulsar timing has been proposed as a viable probe of dark matter subhalos with masses of in the solar neighborhood. We present a comprehensi…
Evidence for a GeV -ray line signal in a stacking analysis of the Virgo, Fornax, and Ophiuchus Galaxy clusters
Yi-Zhong Fan, Zhao-Qiang Shen, Yun-Feng Liang +6
As the largest gravitationally bound objects in the Universe, galaxy clusters have provided the first piece of evidence for the presence of dark matter and may be suitable targets…
Diverse properties of electron Forbush decreases revealed by the Dark Matter Particle Explorer
F. Alemanno, Q. An, P. Azzarello +147
The Forbush decrease (FD) of cosmic rays is an important probe of the interplanetary environment disturbed by solar activities. In this work, we study the properties of 8 FDs elect…
Gamma-Ray Millisecond Pulsars: Off-pulse Emission Characteristics, Phase-Resolved Pseudo-Luminosity--Cutoff Energy Correlation, and High-energy Pulsed Emission
Ming-Yu Lei, Zhao-Qiang Shen, Zi-Qing Xia +1
We investigate the -ray emission from 38 millisecond pulsars using 15 years of Fermi-LAT Pass 8 data in the 0.3--500 GeV range. Off-pulse intervals defined objectively with the…
Constraints on axionlike particles from 16.5 years of Fermi-LAT data and prospects for VLAST
Zhi-Qi Guo, Yue-Lin Sming Tsai, Lei Wu +1
Axionlike particles (ALPs), hypothetical particles beyond the Standard Model, are considered as promising dark matter candidates. ALPs can convert into photons and vice versa in a…
Searching for Axion-Like Particles with X-ray Observations of Alpha Centauri
Yu-Xuan Chen, Lei Lei, Zi-Qing Xia +3
We investigate the production of axion-like particles (ALPs) in stellar cores, where they interact with electromagnetic fields and electrons, with typical masses between $\mathcal…
