located at the University of Western Australia in Perth, Australia, the ORGAN (Oscillating Resonant Group AxioN) experiment is a microwave cavity axion haloscope that searches for axions in the 15–50 GHz mass range from the putative axion-photon coupling term g_agg , which began in 2017 [1]. The experiment has undergone several experimental runs, which will be detailed in this presentation...
The Axion Dark Matter eXperiment (ADMX) is a direct-detection axion dark matter search operating as one of the Department of Energy (DOE) "Generation 2" dark matter projects. ADMX searches for dark matter axions in the micro-eV mass range using a large (V ~ 100L) high-Q (Q ~ 40,000) electromagnetic cavity threaded by a moderate intensity magnetic field (B ~ 8T) to resonantly convert local halo...
The Haloscope At Yale Sensitive To Axion CDM (HAYSTAC) experiment is a microwave cavity search which is actively probing QCD axions with masses ≳$10\mu$eV. In this talk, I will present recent results from HAYSTAC's Phase II search for QCD axions between $16.96-19.46\mu$eV. These results are the widest search to date to achieve a quantum enhanced scan rate from a squeezed state reciever and...
ABRACADABRA-10cm has had great success as a lumped-element axion dark matter pathfinder experiment. Now, using the electrodynamics of gravitational waves and a simple change of pickup structures, we are using the ABRACADABRA detector to search for high-frequency gravitational wave in the kHz to MHz range. These higher frequencies may indicate signs of in-spiraling primordial black holes, or...
We present a novel approach to investigating axions and axion-like particles (ALPs) by studying their potential conversion into X-rays within the Sun’s atmospheric magnetic field. Utilizing high sensitivity data from the Nuclear Spectroscopic Telescope Array (NuSTAR) collected during the
2020 solar minimum, along with advanced solar atmospheric magnetic field models, we establish a new limit...
The BREAD Collaboration is conducting R&D towards wide band dish antenna searches for axions using a unique coaxial antenna design which is well suited for deployment in large solenoid magnets and compatible with sub-kelvin detectors. We will discuss the overall BREAD (Broadband Reflector Experiment for Axion Detector) program and its technology development, focusing on plans for detectors in...
