An axion constraint from the diffuse supernova neutrino background indicated by Super-Kamiokande
Kanji Mori, Tomoya Takiwaki, Kazunori Kohri +1
Recently, the Super-Kamiokande Collaboration reported an indication of the diffuse supernova neutrino background (DSNB) with a statistical significance of . Motivated by this…

Long-term neutrino emission from a core-collapse supernova with axion-photon coupling
Masamitsu Mori, Kanji Mori
We perform long-term general-relativistic neutrino-radiation hydrodynamic simulations for core-collapse supernovae (CCSNe) which include the cooling effect induced by the coupling…

Impacts of axion cooling on the direct detection of supernova axions
Kanji Mori, Masamitsu Mori
Core-collapse supernovae provide a unique opportunity to probe axions because they can be a copious source of the particles. It has recently been proposed that axion helioscopes ca…
