We present an analysis of eight JWST Mid-Infrared Instrument (MIRI) 5.6 micron images with $5\,σ$ depths of ~0.1 uJy. We detect 2854 sources within our combined area of 18.4 square arcminutes. We compute the MIRI 5.6um number counts including an analysis of the field-to-field variation. Compared to earlier published MIRI 5.6 um counts, our counts have a more pronounced knee, at roughly 2 uJy. The location and amplitude of the counts at the knee are consistent with the Cowley et al. (2018) model predictions, although these models tend to overpredict the counts below the knee. In areas of overlap, 84% of the MIRI sources have a counterpart in the COSMOS2020 catalog. These MIRI sources have redshifts that are mostly in the $z\sim0.5-2$, with a tail out to $z\sim5$. They are predominantly moderate to low stellar masses ($10^8-10^{10}$M$_{\odot}$) main sequence star-forming galaxies, suggesting that with ~2hr exposures, MIRI can reach well below $M^*$ at cosmic noon and reach higher mass systems out to $z\sim5$. Nearly 70% of the COSMOS2020 sources in areas of overlap now have a data point at 5.6um (rest-frame near-IR at cosmic noon) which allows for more accurate stellar population parameter estimates. Finally, we discover 31 MIRI-bright sources not present in COSMOS2020. A cross-match with IRAC channel 1 suggests that 10-20% of these are likely lower mass (M$_*\approx10^9$M$_{\odot}$), $z\sim1$ dusty galaxies. The rest (80--90%) are consistent with more massive but still very dusty galaxies at $z>3$.

Exploring the evolution of star formation and dwarf galaxy properties with JWST/MIRI serendipitous spectroscopic surveys
詹姆斯·韦伯太空望远镜的中分辨率光谱仪(MRS)将提供近2个数量级的灵敏度提高和超过3倍的光谱分辨率提高我们以前的天基中红外光谱仪,斯皮策IRS。在本文中,我们预测光谱的观测和偶然发现的MRS。具体来说,指向观测的赫歇尔源只需要几分钟的源集成检测几个恒星形成和活动星系核线,z $=$ 3及以上。但同样的数据也将包括数十个偶然的0 $\lesssim$ z $\lesssim$ 4星系,每个视场的红外光度范围为$\sim10^6-10^{13}$ L $_{\odot}$。特别是,第一次,我们将能够免费探索$L_{IR}<10^{9}L_{\odot}$制度出$z\sim3$。我们估计,与$\sim$ 100这样的领域,这些检测的统计数据将足以约束红外光度函数的低$L$端的演变,因此恒星形成率函数。上述结论适用于红外光度函数的潜在低$L$端的宽范围,并解释了低$L$、低金属丰度星系中PAH亏损的原因。
