Description
The standard cold dark matter (CDM) paradigm predicts a hierarchy of structure down to very small scales (of order the mass of the Earth). Detecting this substructure would not only vindicate the CDM framework, but also potentially allow for a measurement of the free-streaming scale of the dark matter particles, elucidating their production mechanism. Fabian will discuss possible avenues for detecting the substructure, both within the Milky Way halo and other galaxies, purely through its gravitational interactions.
