| Outline of Annual Research Achievements |
This work has let to many important and interesting results. One study enabled by this grant was published under the title 'Global view of axion stars with nearly Planck-scale decay constants', in which I investigated the properties of axion stars arising from symmetry-breaking near the Planck scale. A second study, 'Probing relativistic axions from transient astrophysical sources', was conducted with colleagues at IPMU and proposed a novel signal type for current and near-future axion experiments; this work has led to several follow-up works. This work was also featured in the Snowmass 2023 process in the US.
This grant also enabled many international presentations of this work, allowing for a greater impact within the physics community in Japan, and also greater international reach across Europe and in the US.
