abstract
Pulsars act as accurate clocks, sensitive to gravitational redshift and acceleration induced by transiting clumps of matter. We study the sensitivity of pulsar timing arrays (PTAs) to single transiting compact objects, focusing on primordial black holes and compact subhalos in the mass range from $10^{-12} M _{\odot}$ to well above $100~M_\odot$. We find that the Square Kilometer Array can constrain such objects to be a subdominant component of the dark matter over this entire mass range, with sensitivity to a dark matter sub-component reaching the sub-percent level over significant parts of this range. We also find that PTAs offer an opportunity to probe substantially less dense objects than lensing because of the large effective radius over which such objects can be observed, and we quantify the subhalo concentration parameters which can be constrained.

Probing small-scale power spectrum with gravitational-wave diffractive lensing
Gravitational-wave diffractive lensing, combined statistically across many events, can map the small-scale matter power spectrum through a new frequency-to-scale relation.

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_⊙.

Probing the fate of large primordial perturbations with exoplanets
Observed ultra-wide exoplanets already constrain the amplitude and scale of primordial power-spectrum peaks that produce ultra-compact minihalos, with misalignment signatures as a future probe.

Projecting the ultimate pulsar timing sensitivity to dark matter substructure in a stochastic gravitational wave background
Monte Carlo and ML surrogate framework projects PTA sensitivity to compact DM substructures and shows SGWB weakens it, with only Shapiro searches retaining sensitivity in optimistic cases.

Self-gravitating quantum stars with a globally relevant Bohm potential
The equilibrium radius of self-gravitating dark fermion stars is determined by the fermion mass once the total mass is given, with the Bohm potential supplying outward pressure for heavier species and inward tension f...
