Watch a 15-minute conference talk exploring the development of mock sky simulations for SPHEREx Extragalactic Background Light (EBL) auto- and cross-correlation studies. Learn about the computational methods and theoretical frameworks used to create realistic sky models that will support the SPHEREx mission's cosmological investigations. Discover how these mock skies enable researchers to test analysis pipelines, validate measurement techniques, and predict the scientific capabilities of SPHEREx for studying the cosmic infrared background and its correlations with other cosmological tracers. Gain insights into the technical challenges of simulating the complex astrophysical signals that SPHEREx will observe, including contributions from galaxies across cosmic time and the diffuse extragalactic background light. Understand how these simulations contribute to multi-probe cosmology efforts by enabling cross-correlation studies with other large-scale structure surveys and cosmic microwave background observations.
