Arp 98 another for Arp lovers only
Arp 98 is a pair of interacting galaxies. Arp classed them under
"Spiral galaxy with companion on arms: Elliptical galaxy companions." The spiral is LEDA 5715 and is classed as Sbc with a red shift distance of 547 million light years. One paper says "The 'bridge' has no relation to the normal spiral arms which are bound more tightly." I assume that refers to the bright tiny arms just visible in my shot. Still the bridge does appear to come off of one same as the opposite tidal arm comes off the other one. The elliptical galaxy is LEDA 5714 and is called a red, spherical compact galaxy with halo. It has a red shift distance of 552 million light years. The difference is likely due to gravitational interaction between the two. At the far upper left is CGCG 502-109 at 547 million light years, same as LEDA 5715 so a member of the group. It is classed simply as a spiral galaxy. Directly west (right) of Arp 98 is 2MASXi J0131394+320601 ID a galaxy bright in infra red light. Like all other galaxies in the image I can find no data on it. Arp 98 is located in the constellation of Triangulum just north of the far more famous Triangulum Galaxy, M33.

Rick,
your choice of objects is refreshing, I like this one too. I recently have been acitve in a german astro-site and see the same standard objects being posted over and over. Good to come here and see your Arp galaxies. Stefan "Rick Johnson" schrieb im Newsbeitrag ster.com... Arp 98 is a pair of interacting galaxies.
