Description
Dark matter candidates such as axions and dark photons can generate coherent, oscillating magnetic fields at the Earth’s surface, arising from boundary conditions between the conductive Earth and the ionosphere. The Search for Non-Interacting Particles Experiment (SNIPE) collaboration employs a global network of magnetometers in radio-quiet locations to search for these signals. An update on SNIPE’s progress, including efforts to enhance sensitivity and extend the search to higher frequencies will be presented. The Dark-photons & Axion-Like particles Interferometer (DALI) is a next-generation experiment designed to detect axion dark matter in the 25–250 μeV mass range. Although optimized as a haloscope for virialized galactic axions, DALI is also sensitive to transient interactions with fine-grained axion streams predicted to pass through the Solar System. A report on DALI’s projected sensitivity to these streams will also be presented.
