Our analysis uses $\\gamma$-ray photons from 14 years of observations with the Fermi Large Area Telescope (LAT), together with galaxy shape catalogs from the Dark Energy Survey Year 3 (DES Y3) and the Dark Energy Camera All Data Everywhere (DECADE) project, enabling us to probe cosmological large-scale signals over a common sky area of $\\sim 12{,}000\\,\\mathrm{deg}^2$ shared by the $\\gamma$-ray and galaxy data sets.
