Fast Transient Study with Deep-Imaging Surveys and Synergistic Observations

利用日本的观测设施进行了一系列观测（例如，Subaru/HSC、Seimei/TriCCS）。在2022财政年度发现了大量的Ia型超新星，可以进一步研究长期存在的Ia型超新星的起源和爆炸问题。此外，在我们的调查项目（MUSSES）的2022年观测活动中，已经成功发现了十多个早期核心坍缩超新星和两个快速蓝色超亮瞬态候选者。于二零二二财政年度共发表五篇有关不同种类快速瞬变的论文。

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.
