: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. |
