Reviving sub-keV warm dark matter: a UVLF-based analysis

Raymond T. Co, Siu Cheung Lam, Sai Chaitanya Tadepalli +1

Thermal warm dark matter (WDM) particles with $m_{WDM} \leq 1 keV$ are ruled out at more than $4 σ$ by multiple observational probes, owing to the strong suppression of…

(Non-)Perturbative Dynamics of a Light QCD Axion: Dark Matter and the Strong CP Problem

Raymond T. Co, Taegyu Lee, Owen P. Leonard

Considerable theoretical efforts have gone into expanding the reach of the QCD axion beyond its canonical mass--decay-constant relation. The $Z_{N}$ QCD axion model reduces…
