Pulsar timing residual induced by ultralight vector dark matter
Abstract We study the ultralight vector dark matter with a mass around $$10^{-23}\,\mathrm {eV}$$ 10-23eV . The vector field oscillating coherently on galactic scales induces oscillations of the spacetime metric with a frequency around nHz, which is detectable by pulsar timing arrays. We find that t...
