Cosmology of Inelastic Self-Interacting Dark Matter: Linear Evolution and Observational Constraints
Xin-Chen Duan, Yue-Lin Sming Tsai, Ziwei Wang
We study the linear cosmological evolution of inelastic self-interacting dark matter in a two-component dark sector with a small mass splitting, assuming thermal initial conditions…

Exploring sub-GeV dark matter via -wave, -wave, and resonance annihilation with CMB data
Yu-Ning Wang, Xin-Chen Duan, Tian-Peng Tang +2
We revisit constraints on sub-GeV dark matter (DM) annihilation via -wave, -wave, and resonance processes using current and future CMB data from Planck, FIRAS, and upcoming e…

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…
