Milky Way-mass dark matter density profiles in IllustrisTNG are largely insensitive to astrophysics and cosmology variations, dominated by halo-to-halo variance instead.
X-Stream generates thousands of stream realizations in trial potentials and applies nested sampling to constrain the full radial density profile of dark matter halos from imaging data.
An extended parametric model for SIDM halos incorporates mass accretion to delay core collapse and reduces errors in predicted V_max at z=0 relative to the prior Yang et al. (2024b) model.
Simulations indicate LISA could statistically distinguish CDM from SIDM (constant 1 cm²/g cross-section) with at least ~70 high-SNR massive black hole merger detections.
