abstract
Pulsar Timing Array experiments probe the presence of possible scalar or 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 $10^{-24.0}~\text{eV} \lesssim m \lesssim 10^{-23.3}~\text{eV}$ cannot constitute $100\%$ of the measured local dark matter density, but can have at most local density $\rho\lesssim 0.3$ GeV/cm$^3$.

Correlated signals of ultralight scalar dark matter in pulsar timing
A finite-spatial-correlation Gaussian-field prior for PTA ULDM signals interpolates between fully correlated and uncorrelated limits and is validated on blinded mock data for linear and quadratic couplings.

Pulsar Timing Sensitivity to Dark Matter Substructure in the Presence of a Stochastic Gravitational-Wave Background
A stochastic GWB suppresses PTA reach to DM substructure by 1–3 orders of magnitude relative to white-noise forecasts, with dynamic Shapiro least affected near 10^{-2} M_⊙.

Constraints on minimally and conformally coupled ultralight dark matter with the EPTA
The EPTA data rule out ultralight dark matter beyond a few tenths of the local density and place orders-of-magnitude stronger limits on scalar couplings to matter.
