Using $Δ N_{eff}$ to constrain preferred axion model dark matter

Andrew Cheek, Ui Min

Preferred axion models are minimal realizations of the Peccei-Quinn solution to the strong CP problem while providing a dark matter candidate. These models invoke new heavy quarks…

Gemini Dark Matter

Andrew Cheek, Yu-Cheng Qiu, Liang Tan

The $S_{8} / σ_{8}$ tension in the large scale structure can be explained by decaying dark matter with an almost degenerate spectrum and small enough decay width. Here we propose the Gem…
