From: AEDGE: Atomic Experiment for Dark Matter and Gravity Exploration in Space
The sensitivities of AEDGE in broadband (purple lines) and resonant mode (orange lines) to quadratic scalar DM interactions with electrons (left) and photons (right), compared to those of a km-scale terrestrial experiment (green lines). The grey regions show parameter spaces that have been excluded by the MICROSCOPE experiment (blue lines) [24, 25], searches for violations of the equivalence principle with torsion balances (red lines) [26, 27], or by atomic clocks (brown lines) [28, 29]
