Abstract
Pulsar Timing Array experiments probe the presence of possible
scalar/pseudoscalar ultralight dark matter particles through decade-long timing
of an ensemble of galactic millisecond radio pulsars. With the second data
release of the European Pulsar Timing Array, we focus on the most robust
scenario, in which dark matter interacts only gravitationally with ordinary
baryonic matter. Our results show that ultralight particles with masses
$10^{-24.0}~\text{eV} \lesssim m \lesssim 10^{-23.2}~\text{eV}$ cannot
constitute $100\%$ of the measured local dark matter density, but can have at
most local density $\rho\lesssim 0.15$ GeV/cm$^3$.
