Supernovae in the Subaru Deep Field

The Type Ia supernova (SN Ia) rate, when compared to the cosmic star formation history (SFH), can be used to derive the delay-time distribution (DTD; the hypothetical SN Ia rate...Ia型超新星（Type Ia supernova, SN Ia）的爆发率，与宇宙恒星形成历史（cosmic star formation history, SFH）进行对比时，可用于推导延迟时间分布（delay-time distribution, DTD；即假设的Ia型超新星爆发率……）
