Constraints on dark photon dark matter using data from LIGO's and Virgo's third observing run Vrije Universiteit Brussel Universiteit Antwerpen Universiteit Gent KU Leuven
We present a search for dark photon dark matter that could couple to gravitational-wave interferometers using data from Advanced LIGO and Virgo's third observing run. To perform this analysis, we use two methods, one based on cross-correlation of the strain channels in the two nearly aligned LIGO detectors, and one that looks for excess power in the strain channels of the LIGO and Virgo detectors. The excess power method optimizes the Fourier ...
