Searching for dark matter in a clumpy universe

Dark matter halos in the standard LCDM model contain abundant substructure, or subhalos, which are crucial for indirect dark matter searches through annihilation signals. The most massive subhalos host dwarf galaxies, currently prime targets, while smaller dark subhalos may also provide excellent opportunities due to their proximity and high dark matter content. Moreover, the clumpy distribution of subhalos enhances the overall annihilation signal. This talk will present numerical work on Milky Way-like subhalo populations and discuss their impact on gamma-ray dark matter search strategies with instruments such as Fermi LAT, MAGIC, and CTAO, including recent searches and derived constraints.
