Reconstructing the Projected Dark Matter Field across 0.1–100 Mpc Scales from the SDSS Survey*
Abstract Dark matter sets the gravitational environment in which galaxies form and evolve, but cannot be observed directly. We present a conditional diffusion model that reconstructs the projected dark matter density field from the galaxy stellar-mass density field for direct application to galaxy surveys. The model is...
