AI总结:

通过分析JWST多个巡天数据,结合EAZY和ProSpect拟合3751个遥远星系,自洽测量了z=5.5-13.5的宇宙恒星形成与AGN光度历史,发现两者显著上升,并总结了逾13 Gyr的演化。

摘要:

在$z = 5.5-13.5$处自洽地测量了宇宙恒星形成历史(CSFH)和宇宙活动星系核(AGN)光度历史(CAGNH)。这是通过分析James Webb Space Telescope在PEARLS、CEERS、NGDEEP、JADES和PRIMER巡天的约$400 \\, \mathrm{arcmin^{2}}$视场中探测到的星系实现的。具体而言,结合光谱能量分布拟合代码EAZY和\textsc{ProSpect},估算了$3751$个遥远星系的光度红移和天体物理量,据此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。对分布函数积分发现,CSFH在$z = 13.5 - 5.5$期间上升约$1$~dex,CAGNH在$z = 10.5 - 5.5$期间上升约$1$~dex。我们将$z=13.5-5.5$的CSFH和CAGNH结果与$z= 5-0$的结果相连,总结了从星系形成初期至今逾$\gtrsim 13$ Gyr的恒星形成与AGN活动。

英文摘要:

The cosmic star formation history (CSFH) and cosmic active galactic nuclei (AGN) luminosity history (CAGNH) are self consistently measured at $z = 5.5-13.5$. This is achieved by analyzing galaxies detected by the James Webb Space Telescope from $\approx 400 \, \mathrm{arcmin^{2}}$ fields from the PEARLS, CEERS, NGDEEP, JADES and PRIMER surveys. In particular, the combination of spectral energy distribution fitting codes, EAZY and \textsc{ProSpect}, are employed to estimate the photometric redshifts and astrophysical quantities of $3751$ distant galaxies, from which we compute the stellar mass, star formation rate and AGN luminosity distribution functions in four redshift bins. Integrating the distribution functions, we find that the CSFH rises by $\approx 1$~dex over $z = 13.5 - 5.5$ and the CAGNH rises by $\approx 1$~dex over $z = 10.5 - 5.5$. We connect our results of the CSFH and CAGNH at $z=13.5-5.5$ to that from $z= 5-0$ to determine the summary of $\gtrsim 13$ Gyr of star formation and AGN activity, from the very onset of galaxy formation to the present day.
