Theoretical analysis reveals how dark matter scaffolding compressed primordial plasma to seed early stars, highlighting future empirical validation through the Roman Space Telescope.
This technical report (Version 1.1) explores the foundational role of Cold Dark Matter (CDM) as the primary gravitational scaffolding in the early universe. We analyze the physical mechanisms through which dark matter halos gravitationally attracted and compressed primordial baryonic plasma, accelerating molecular hydrogen (H₂) cooling and triggering early Population III star formation. Furthermore, this work contextualizes these theoretical frameworks within the upcoming observational capabilities of NASA's Nancy Grace Roman Space Telescope, launched on August 30, 2026. We discuss how Roman's Wide Field Instrument (WFI) will utilize weak gravitational lensing and cosmic shear data to map the three-dimensional distribution of dark matter, providing unprecedented empirical constraints on early cosmic structure formation.
