Despite decades of intensive direct detection searches across different dark matter candidates, no conclusive particle signal has been identified. This motivates complementary constraints on dark matter properties model independently from astronomical observations. In this talk, we focus on wave-like ultralight dark matter (ULDM) and its dynamical impact on dwarf galaxies. We will show that...
