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…
The nanohertz stochastic gravitational wave background from cosmic string loops and the abundant high redshift massive galaxies
Ziwei Wang, Lei Lei, Hao Jiao +2
Recently, pulsar timing array (PTA) experiments have provided compelling evidence for the existence of the nanohertz stochastic gravitational wave background (SGWB). In this work,…
Primordial magnetic field as a common solution of nanohertz gravitational waves and the Hubble tension
Yao-Yu Li, Chi Zhang, Ziwei Wang +4
The origin of interstellar and intergalactic magnetic fields remains largely unknown. One possibility is that they are related to the primordial magnetic fields (PMFs) produced by,…
