Arp 235/NGC 14 Peculiar nearby galaxy
ARP 235/NGC 14 is an irregular peculiar galaxy in Pegasus. Arp
classified it under: "Galaxies (not classifiable as S or E); Appearance of fission. He also noted; "Faint outer oval and resolution into stars". Was he referring to all the star clusters in the core of this galaxy? I see nothing else in his photo with the 200" scope that would fit. http://nedwww.ipac.caltech.edu/level...ig_arp235.jpeg. Film grain is very obvious in the image but I see no sign of stars. This galaxy is nearby at only about 24 million light years. Therefore some earth based scopes should be able to resolve stars in it using today's detectors. In fact the star clusters look almost like stars in the Sloan Deep Sky Survey; http://casjobs.sdss.org/ImgCutoutDR4...00&height=1000 But they are far too bright to be individual stars. Toward the lower left corner is a small blue galaxy with an even bluer blob within the halo just right of its core. It too is about 25 million light years away per its redshift. It is KUG 0007+154. The small blue blob carries the designation of SDSS J000952.87+154406.9 and is listed as a separate galaxy. Both have about the same redshift. Makes me think it is more likely a star forming region in HUG 0007+154. To be this small at this distance KUG 0007+154 would have to be a very small dwarf galaxy with the possible companion being a sub dwarf. The galaxy above ARP 235 is SDSS J000846.00+155142.2 at 530 million light years. It is very blue and seems to have an off center core. Yet I see nothing around it that could have caused this. To the west (right) of Arp 235 a short distance (in my image) is a small red galaxy. This is SDSS J000834.99+155011.8 at 2.07 billion light years. It has been severely reddened by all the intergalactic dust and gas its light passed through to get to us. At about 10 o'clock from Arp 235 is a very blue "star" at about the same distance from Arp 235 as the above galaxy. Two stars to its lower left point about at it, the lower of the two is somewhat orange in color. This is the quasar SDSS J000856.79+155045.7 at 9.0 billion light years, the most distant object in the image of which I'm aware. To the lower left above KUG 0007+154 is the trail of asteroid (93258) 2000 SX165. At a distance of about 7.5 light minutes, it is the closest object to us in the image. That means the quasar is about 600 trillion times further away than the asteroid! Now that's a large depth of field! 14" LX 200R @ f/10, L=4x10 RGB=2x10, STL-11000XM, Paramount ME Rick -- Correct domain name is arvig and it is net not com. Prefix is correct.

Rick, that's a strange beast with it's star clusters near the core. Very

Maybe the experts don't either. I found little of use in the literature though right now we are tending the grandkids while mom is stuck working at 3 a.m. when she can't get child care for the two older ones. So I have little time for such searches and may have missed it. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |
