摘要
宇宙恒星形成历史（CSFH）和宇宙活动星系核（AGN）光度历史（CAGNH）在 处被自洽地测量。这是通过分析詹姆斯·韦布太空望远镜从约 区域的PEARLS、CEERS、NGDEEP、JADES和PRIMER巡天中探测到的星系实现的。特别地，结合谱能量分布拟合代码EAZY和\textsc{ProSpect}，用于估计3751个遥远星系的测光红移和天体物理量，由此我们计算了四个红移区间内的恒星质量、恒星形成率和AGN光度分布函数。积分分布函数后，我们发现CSFH在 区间上升约1 dex，CAGNH在 区间上升约1 dex。我们将 处的CSFH和CAGNH结果与 处的结果联系起来，以确定约13 Gyr的恒星形成和AGN活动的总结，从星系形成的最初阶段至今。
