| Description | The first challenge here is understanding what "disturbed by interior absorption" means. I searched carefully on the Internet for a definitive source and found found nothing very convincing. As is typical in the Arp world, many sources quote the category but explain nothing, as if Arp's perceptions were self-evident (they often aren't, I find). So I'm falling back onto the common meanings of these words, which would be a galaxy where the interior of the disk is seriously disturbed or disrupted. Examining the galaxies so categorized (153-160), I can confirm that this describes all of them to some degree. Certainly, in the case of Arp 153. the galaxy appears to be lenticular, but the core is bifurcated and divided by large dust lanes. This seems consistent with a galaxy consolidating its core after a merger. |
