论文摘要
我们根据詹姆斯·韦伯（James Webb）空间望远镜（JWST）获得的早期发行观测值（JWST）在7.7-，10- $ $ $ $ M（分别为F770W，F1000W和F1500W）中，我们介绍了中红外星系数计数。由于JWST的较高敏感性，80％的完整性限制在F770W，F1000W和F1500W过滤器中分别达到0.32、0.79和2.0 $ $ $ JY，即$ \ sim $ \ sim $ 100 $ 100倍比以前的太空红外望远镜（如Spitzer或Akari）深。由于多环芳烃的排放，该数字计数的收入比$ 0.05 \ sim0.5 $ mjy的宽颠簸深得多。从文献中的进化模型中推断出淡淡的通量的推断与新数据非常吻合，在新数据中，红外光度函数的推断淡淡的终端结合了宇宙恒星形成史，可以通过jwst重现更深的数量计数。由于JWST的出色敏感性，观察到的数据证实了我们对微弱红外源的理解。
We present mid-infrared galaxy number counts based on the Early Release Observations obtained by the James Webb Space Telescope (JWST) at 7.7-, 10- and 15-$μ$m (F770W, F1000W and F1500W, respectively) bands of the Mid-Infrared Instrument (MIRI). Due to the superior sensitivity of JWST, the 80 percent completeness limits reach 0.32, 0.79 and 2.0 $μ$Jy in F770W, F1000W and F1500W filters, respectively, i.e., $\sim$100 times deeper than previous space infrared telescopes such as Spitzer or AKARI. The number counts reach much deeper than the broad bump around $0.05\sim0.5$ mJy due to polycyclic aromatic hydrocarbon (PAH) emissions. An extrapolation towards fainter flux from the evolutionary models in the literature agrees amazingly well with the new data, where the extrapolated faint-end of infrared luminosity functions combined with the cosmic star-formation history to higher redshifts can reproduce the deeper number counts by JWST. Our understanding of the faint infrared sources has been confirmed by the observed data due to the superb sensitivity of JWST.
