Transition magnetic-dipole dark matter and the LZ230616 high-recoil candidate
Yuxuan He
A transition magnetic dipole connects an endothermic nuclear recoil to a delayed photon. We study this interpretation of LZ230616, the 248-keV candidate in LZ's extended-energy sea…

Probing Collapsed Dark Matter Halos with Fast Radio Bursts
Yuxuan He, Weiyang Wang, Chen Zhang +1
Observations of ultra-dense substructures in strong lensing systems challenge the standard cosmological model at small scales. Self-interacting dark matter (SIDM), as an alternativ…

Implications of the KM3NeT Ultrahigh-energy Event on Neutrino Self-interactions
Yuxuan He, Jia Liu, Xiao-Ping Wang +1
Neutrino self-interactions (SI) mediated by light bosonic particles can produce characteristic spectral dips in astrophysical neutrino fluxes, thereby altering the expected ener…
