DMRadio-Core: A new approach for GUT-scale axion searches
V. Ankel, C. Bartram, J. Begin +33
Searches for QCD axions with masses in the neV/ mass range are strongly motivated by new physics at the GUT scale and by well-motivated pre-inflationary axion symmetry breakin…
The Cryogenic System of DMRadio-50L
V. Ankel, C. Bartram, J. Begin +36
The DMRadio-50L experiment is designed to search for axion dark matter in the 5 kHz - 5 MHz frequency range using a lumped-element LC resonator and a toroidal magnet and to serve a…
Electromagnetic modeling and science reach of DMRadio-m
DMRadio Collaboration, A. AlShirawi, V. Ankel +45
DMRadio-m is an experiment that is designed to be sensitive to KSVZ and DFSZ QCD axion models in the 10--200\,MHz (41 neV -- 0.83 eV/) range. The experiment uses…
Noise limits for dc SQUID readout of high- resonators below 300 MHz
V. Ankel, C. Bartram, J. Begin +38
We present the limits on noise for the readout of cryogenic high- resonators using dc Superconducting Quantum Interference Devices (SQUIDs) below 300 MHz. This analysis uses rea…
A Model-Independent Radio Telescope Dark Matter Search in the L and S Bands
Aya Keller, Nicole Wolff, Karl van Bibber
Ultralight bosonic dark matter in its most general form can be detected through its decay or annihilation to a quasimonochromatic radio line. Assuming only that this line is consis…
