From: Searching for dark photon dark matter in LIGO O1 data

Fig. 1

The dark photon dark matter (DPDM) signal power spectrum is shown in terms of characteristic strains \({h}_{{\rm{c}}}\) (red), with \(U{(1)}_{{\rm{B}}}\) coupling parameter \({\epsilon }^{2}=1{0}^{-41}\), DPDM oscillation frequency \({f}_{0}=500\) Hz, and typical velocity of DPDM \({v}_{0}=1{0}^{-3}\) of the speed of light. The Advanced LIGO design sensitivity in a small frequency window is approximately flat, which is shown as the black dashed line.
