Event Details & Abstract: 

About 85% of the matter in the universe is made up of an unknown "dark" component that is mostly non-baryonic. For several decades, searches for this mysterious substance has principally focused on one candidate particle: the WIMP. Superconducting Quantum Interference Devices (SQUIDs) have played an important role in these searches, which have successfully ruled out significant phase space for WIMP dark matter. Recently, there has been a surge in theoretical interest in ultra-light-field dark matter, including QCD axions (spin 0 bosons) and hidden photons (spin 1 bosons). The Dark Matter Radio (DM Radio) is a tunable superconducting high-Q lumped-element resonator also using SQUIDs for detection. I will discuss the motivation, status and prospects for the DM Radio experiment in searching for both axions and hidden photons, and the remarkable phase space that DM Radio will search over the next several years.
