Abstract (from CDS):
This brings our sample of dEs with ionized gas with Hα+[Nii] narrow-band imaging to five objects. The ionized gas morphologies in these galaxies range from pure nuclear emission peaks to extended emission complexes. This morphological diversity could also indicate a diversity in ionizing processes in dEs with a warm interstellar medium (active galactic nuclei, starbursts, post-asymptotic giant branch stars, etc.).
Inside FCC206, four star clusters appear to be on the verge of merging to form a nucleus in this presently non-nucleated dE. Understanding the formation of nuclei in dEs could give us important clues to the formation of supermassive black holes (SMBHs).
