Searching for axion and dark photon dark matter with the SNIPE - experiment.

The Earth can act as a transducer for ultralight particles, such as hidden photons and axion-like particles, that are candidates for dark matter. The boundary conditions of the conductive Earth, non-conducting atmosphere, and conducting ionosphere can lead to these particles generating oscillating, coherent, global magnetic fields. The Search for Non-Interacting Particles Experiment (SNIPE) collaboration uses a network of magnetometers located in magnetically quiet environments to search for such signals. The SNIPE Experiment has set limits for dark photon dark matter and axion dark matter in the 0.5 - 5 Hz band. We describe our efforts to expand the search range to higher frequencies in future searches with improved sensitivity.
