Correlated signals of ultralight scalar dark matter in pulsar timing

Joshua W. Foster, Kimberly K. Boddy, Jeff A. Dror +5

Pulsar timing arrays (PTAs) are sensitive to ultralight dark matter (ULDM) in the $10^{-24}$-$10^{-20}\mathrm{eV}$ mass range, with existing datasets already probing otherwise op…
