资源简介：
本研究使用的数据集是由MIRI Deep Survey (MIDIS) 和 Next Generation Deep Extragalactic Exploratory Public survey (NGDEEP) 组合而成的超深度JWST/NIRCam数据集。该数据集通过结合两个调查的数据，覆盖了从2微米到长波长的所有NIRCam广角滤波器，达到了比其他小区域深 Survey如JADES或GLIMPSE更深2.5倍，比大面积浅Survey如CEERS或PRIMER浅10倍的深度。该数据集用于选取F200W和F277W下降源，识别z∼17和z∼25的星系候选者，用于构建UV亮度函数和推导宇宙早期亮度密度的演化。
The dataset utilized in this study is an ultra-deep JWST/NIRCam dataset compiled from the MIRI Deep Survey (MIDIS) and the Next Generation Deep Extragalactic Exploratory Public survey (NGDEEP). By integrating data from the two surveys, this dataset covers all NIRCam wide-angle filters spanning from 2 μm to long wavelengths, achieving a depth 2.5 times greater than small-area deep surveys such as JADES or GLIMPSE, and 10 times shallower than large-area shallow surveys including CEERS or PRIMER. This dataset is employed to select sources with flux decline in the F200W and F277W bands, identify galaxy candidates at redshifts z~17 and z~25, construct the UV luminosity function, and derive the evolution of luminosity density in the early universe.
