Object name: ARP140
Designation(s): ARP140, NGC0274, NGC0275,
Arp 140 is a pair of interacting galaxies, NGC 274 and NGC 275 right to left. They are 65 million light years distant and in the constellation of Cetus. Arp classed them under; material emanating from elliptical galaxies. A category that makes little sense to me. M87 has a nice jet and would seem to fit but it's under galaxies with jets which is more accurate though its the black hole, not the galaxy itself that is the cause of the jet. Other than jets what can an elliptical, or its black hole, emanate? All galaxies I've imaged so far in this category involve highly distorted galaxies, #142 through #145. All appear to be due to interacting galaxies. Arp 140 appears to fall into this pattern. Or does it? In the other cases, both the elliptical and the spiral are distorted. Usually, the spiral is considerably more distorted which isn't surprising. But both show distortion. Not in this case. Here the elliptical, NGC 274, really an S0 galaxy not elliptical, seems little distorted though it is classed a being peculiar. But its companion, at the same redshift distance, NGC 275 is highly distorted and generating new stars like crazy. This seems hard to explain. It's likely they are much farther apart than their nearly equal redshift indicates with probably the distorted spiral being closer to us. I say this because its blue color overlays some of the golden S0 galaxy. The S0's higher density may be helping keep it from distorting very much. While some theories say an S0 is the result of a galaxy merger it appears NGC 274 was already S0 long before this encounter. That doesn't mean it didn't have a previous one billions of years earlier that created it. But now look really closely at the enlargement. There does appear to be a very faint linear feature coming from the S0 pointed to the east-northeast. There seems to be a faint tidal spray around the galaxy as well. So maybe Arp was right after all though I see no hint of the feature in Arp's image. I need to take a much deeper image though that is likely impossible due to satellite traffic. This pair is right in the geostationary belt as seen from my latitude.
