Axion Magnetic Resonance: A Novel Enhancement in Axion-Photon Conversion
Hyeonseok Seong, Chen Sun, Seokhoon Yun
We identify a new resonance, axion magnetic resonance (AMR), that can greatly enhance the conversion rate between axions and photons. A series of axion search experiments rely on c…
Dark Matter In Extreme Astrophysical Environments
Masha Baryakhtar, Regina Caputo, Djuna Croon +37
Exploring dark matter via observations of extreme astrophysical environments -- defined here as heavy compact objects such as white dwarfs, neutron stars, and black holes, as well…
Gravitational Waves from Incomplete Inflationary Phase Transitions
Joel Barir, Michael Geller, Chen Sun +1
We study the observable implications of an incomplete first order phase transition during inflation. In such a phase transition, the nucleated bubbles do not percolate and instead…
Galactic rotation curves versus ultralight dark matter: A systematic comparison with SPARC data
Nitsan Bar, Kfir Blum, Chen Sun
We look for and place observational constraints on the imprint of ultralight dark matter (ULDM) soliton cores in rotation-dominated galaxies. Extending previous analyses, we find a…
Axion Echos from the Supernova Graveyard
Manuel A. Buen-Abad, JiJi Fan, Chen Sun
Stimulated decays of axion dark matter, triggered by a source in the sky, could produce a photon flux along the continuation of the line of sight, pointing backward to the source.…
Challenges for an axion explanation of the muon measurement
Manuel A. Buen-Abad, JiJi Fan, Matthew Reece +1
The discrepancy between the muon measurement and the Standard Model prediction points to new physics around or below the weak scale. It is tantalizing to consider the loop ef…
