Fast Transient Study with Deep-Imaging Surveys and Synergistic Observations

在2022财年，使用日本观测设施（如Subaru/HSC，晴明/TriCCS）进行了一系列观测。已经发现了十几颗早期超新星，并通过国际合作成功地进行了后续观测。随着在2022财年发现大量早期Ia型超新星，可以进一步研究Ia型超新星长期存在的祖先和爆炸问题。此外，在我们的调查项目（MUSSES）的2022观测活动中，已经成功发现了十多颗早期核心坍缩超新星和两颗快速蓝色超亮瞬态候选者。在FY2022年共发表了5篇与不同类型的快瞬态相关的论文。

A series of observations were carried out with Japanese observing facilities (e.g., Subaru/HSC, Seimei/TriCCS) in FY2022. A dozen of early-phase supernovae have been discovered and follow-up observations have been carried out via international collaborations successfully.With a promising number of early-phase type Ia supernovae discovered in FY2022, the long-standing progenitor and explosion issues of type Ia supernovae can be further investigated. Moreover, over ten early-phase core-collapse supernovae and two fast blue ultra-luminous transient candidates have been successfully discovered in the 2022 observing campaign of our survey project (MUSSES). Total five papers related to different kinds of fast transients have been published in FY2022.
