我们研究了在红移范围0≤z≤5内，核心坍缩超新星（CCSN）率如何追踪恒星形成率密度（SFRD）。为此，我们使用了詹姆斯·韦布空间望远镜高级深度河外调查（JADES）瞬态调查（JTS）的新高红移结果以及已发表的CCSN率。利用观测到的CCSN率来约束将SFRD与CCSN率联系起来的CCSN产生效率，我们研究了恒星形成率与CCSN产生效率之间的推断联系如何取决于恒星初始质量函数（IMF）和采用的CCSN前身质量范围。我们发现，对于合理的CCSN前身质量，观测到的CCSN率与基于尘埃消光校正的UV+IR的SFRD一致。利用观测到的CCSN率直接重建宇宙恒星形成历史，我们恢复了一个在z~2处的峰值，与基于星系光度的测定结果一致。当SFRD估计一致处理时，允许IMF随红移演化只有适度影响，表明CCSN率对IMF变化的敏感性不如预期。采用更高的SFRD，包括尘埃遮蔽的微弱毫米波源群体，意味着在更高红移处有大量且不断增加的缺失、尘埃遮蔽的CCSN。尽管推断的调查遗漏的CCSN比例取决于采用的CCSN产生效率，但我们发现由于遮蔽而遗漏的超新星比例不断增加，从低红移处的适度值上升到z~2处的峰值，并在z~5处仍然很大。
英文摘要
We investigate how core-collapse supernova (CCSN) rates trace the star-formation rate densities (SFRDs) over the redshift range $0 \le z \le 5$. For this we use new high-redshift results from the James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES) Transient Survey (JTS, see the companion paper by DeCoursey et al. 2026), together with published CCSN rates. Using the observed CCSN rates to constrain the CCSN production efficiency relating SFRDs to CCSN rates, we examine how the inferred connection between star formation rates and CCSN production efficiency depends on the stellar initial mass function (IMF) and the adopted CCSN progenitor mass range. We find that the observed CCSN rates are consistent with dust extinction-corrected UV+IR based SFRDs for plausible CCSN progenitor masses. Using the observed CCSN rates to directly reconstruct the cosmic star-formation history, we recover a peak at z $\sim2$, in agreement with galaxy luminosity-based determinations. Allowing the IMF to evolve with redshift has only a modest impact when SFRD estimates are treated consistently, indicating that CCSN rates are not as sensitive to the change of IMF as might be assumed. Adopting higher SFRDs that include a dust-obscured population of faint millimeter sources implies a substantial and increasing fraction of missing, dust-obscured CCSNe at higher redshifts. Although the inferred fraction of CCSNe missed by the surveys depends on the adopted CCSN production efficiency, we find an increasing fraction of supernovae missed due to obscuration, rising from modest values at low redshift to a peak at z $\sim2$, and remaining substantial toward z $\sim5$.
