Pulse and Polarization Structures in Axion-Converted X-rays from Pulsars
JiJi Fan, Lingfeng Li, Chen Sun
Neutron stars (NS's) with their strong magnetic fields and hot dense cores could be powerful probes of axions, a classic benchmark of feebly-coupled new particles, through abundant…

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…

Sterile neutrino dark matter within the SMEFT
Kaori Fuyuto, Jacky Kumar, Emanuele Mereghetti +2
Sterile neutrinos with masses at the scale and mixing to the active neutrinos offer an elegant explanation of the observed dark matter (DM) density. However, the ver…
