:4个星系：Two galaxies (NGC 1365 and NGC 7496) host active galactic nuclei (AGNs) and strong bars. NGC 628 is a prototypical grand-design spiral, while IC 5332 shows a flocculent spiral morphology. Based on MUSE Hα emission line maps, a catalog of ∼ 30, 000 nebulae has been constructed. The nebulae were selected using HIIphot.

:arXiv:2212.09159: 利用JWST/MIRI images in the F770W, F1000W and F1130W来计算q(PAH)=(F770+F1130)/F2100来计算PAH在尘埃中的比例，F2100是用来表示非常小的尘埃颗粒的发射，从而代表总尘埃。SIII/SII表征电离参数，发现q(PAH)最主要和电离参数相关，而和金属丰度关系不大
