Searching for Dark Photon Dark Matter in LIGO O1 Data

Understand

Dark matter exists in our Universe, but its nature remains mysterious.

• The remarkable sensitivity of the Laser Interferometer Gravitational-Wave Observatory (LIGO) may be able to solve this mystery.
• A good dark matter candidate is the ultralight dark photon.
• Because of its interaction with ordinary matter, it induces displacements on LIGO mirrors that can lead to an observable signal.
