Between the worlds of the visible and invisible lies: Dark Matter

Sep 26, 2021
Two powerful probes of dark matter on small scales—strong gravitational lensing and ultra-faint dwarf galaxies—join together to set world-leading constraints on the nature of the dark matter particle in a recent study led by KIPAC researchers, including the authors. In the process, we have shown that combining these probes provides a framework to detect “dark halos,” clumps of dark matter that have no associated visible light, using the vast amounts of deeper data promised by upcoming surveys.
