The gamma-ray signal of decaying dark matter scales with the dark matter density, while voids contain very few of the astrophysical sources that dominate the gamma-ray sky elsewhere. With Elena Pinetti, we are preparing a search for decaying dark matter that combines DESI void catalogues, Fermi-LAT gamma-ray data and Euclid weak-lensing shear, which measures the dark matter profile of the voids. The project is at the planning stage.
