Inching toward the QCD Axions with Axion Magnetic Resonance in Helioscopes
Hyeonseok Seong, Chen Sun, Seokhoon Yun
Utilizing a helical magnet profile to enhance axion-photon conversion showed great promise in laboratory searches for high axion masses. We extend the mechanism, known as the axion…
Detectability of accretion-induced bosenovae in the Milky Way
Dennis Maseizik, Joshua Eby, Hyeonseok Seong +1
We estimate collapse rates of axion stars in our galaxy based on the axion minicluster mass function of the Milky Way dark matter halo. We consider axion-like particles with differ…
Radio Lines from accreting Axion Stars
Dennis Maseizik, Sagnik Mondal, Hyeonseok Seong +1
Axion-like particles, which we call axions, can compose the missing dark matter and may form substructures such as miniclusters and axion stars. We obtain the mass distributions of…
Axion emission from strange matter in core-collapse SNe
Mael Cavan-Piton, Diego Guadagnoli, Micaela Oertel +2
The duration of the neutrino burst from the supernova event SN 1987A is known to be sensitive to exotic sources of cooling, such as axions radiated from the dense and hot hadronic…
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…
