Effects of Cosmic Muons on eV-to-meV Scale Axion Dark Matter Searches
Dan Zhang, Gray Rybka, Edward J. Daw +1
We estimate the synchrotron radiation of cosmic muons in a uniform magnetic field in the eV-to-meV energy scale. Such events can potentially bring backgrounds to the axion dark…
Axion search with telescope for radio astronomy (ASTRA): forecast for observations between 0.5 and 4~GHz
Utkarsh Bhura, David J. E. Marsh, Bradley R. Johnson +8
Axion dark matter (DM) is predicted to convert into radio waves in neutron star magnetospheres. We assess the detectability of this signal using a 5 m radio telescope to be install…
Impact of cavities on the detection of quadratically coupled ultra-light dark matter
Clare Burrage, Angus Macdonald, Michael P. Ross +2
Ultra-light scalar fields may explain the nature of the dark matter in our universe. If such scalars couple quadratically to particles of the Standard Model the scalar acquires an…
Maximizing Quantum Enhancement in Axion Dark Matter Experiments
Chao-Lin Kuo, Chelsea L. Bartram, Aaron S. Chou +8
We provide a comprehensive comparison of linear amplifiers and microwave photon-counters in axion dark matter experiments. The study is done assuming a range of realistic operating…
Searching for the QCD Dark Matter Axion
Masha Baryakhtar, Leslie Rosenberg, Gray Rybka
Proposed half a century ago, the quantum chromodynamics (QCD) axion explains the lack of charge and parity violation in the strong interactions and is a compelling candidate for co…
Larmor Power Limit for Cyclotron Radiation of Relativistic Particles in a Waveguide
N. Buzinsky, R. J. Taylor, W. Byron +25
Cyclotron radiation emission spectroscopy (CRES) is a modern technique for high-precision energy spectroscopy, in which the energy of a charged particle in a magnetic field is meas…
