We present a concept for a space experiment called AEDGE using cold atom interferometry to search for ultralight dark matter (ULDM) and gravitational waves (GWs) in the frequency range between LISA and terrestrial laser interferometers. We illustrate AEDGE’s sensitivity to ULDM and how its GW measurements could explore the assembly of super-massive black holes, first-order phase transitions in the early Universe and cosmic strings. AEDGE will build upon terrestrial cold atom experiments and benefit from the space experience obtained with LISA and cold atom experiments in microgravity.
