Object name: ABELL1367 NGC3840

Designation(s): ABELL1367_NGC3840, UGC06697, NGC3840, NGC3841, NGC3842, NGE3845, NGC3851, NGC3861, UGC06719,

Edit: I originally posted this image back in April 2008. There were processing issues with it as well as not having an annotated image for this very crowded field. I decided it needed a reprocess. With rotten imaging weather I took some time away from processing my backlog to rework this image.

Abell 1367 is a very large, galaxy cluster in Leo not far from the outskirts of the far more famous and 5 times closer Virgo Galaxy Cluster. It is a bit over 300 million light-years distant. NGC 3842 is its major galaxy. It is some 230,000 light-years in diameter. Though measuring it is difficult as its halo overlaps that of its neighbor NGC 3841. Just to the northwest is a huge blue galaxy, UGC 6697. It measures out at 220,000 light-years across. It is classed as an irregular Magellan class galaxy. These are normally small to dwarf sized galaxies rather than huge disk galaxy that this one appears to be. Below it is a blue star-like object that some surveys show as a star others galaxy. If a star the 290 million light-year distance is obviously wrong. Still it looks like a star in my image. Other star/galaxy questionable objects are seen in the image

On the eastern side of NGC 3842 is a quasar with a redshift distance of 7.56 billion light-years. NED shows at the same position that its light apparently travels through two closer dust and gas clouds. Though the redshift of one indicates it is further away than the quasar. Two possibilities. Since both are listed as an absorption feature. This normally only happens when the object is closer so we see the quasar through it. It then adds its own absorption lines to the quasars. This means that while it is closer it is moving toward the quasar giving it a greater velocity in relation to the quasar. Several other quasars are seen in the image.

One galaxy cluster is labeled north of UGC 6697. While the photographic redshift for it and the Big Cluster Galaxy was exactly the same the positions were somewhat different. I used a line from the GC label to the cluster's center position and another to the BCG. Though the position to the cluster was listed with an error bar sufficient to include the BCG I opted to show both. Usually the two agree considerably more closely than this pair do.

Several pairs of galaxies can be seen in the image. In some cases one is star-like, in others appear unrelated and just line of sight pairs such as NGC 3861 and 3861B on the left side of the image. Near the top is the apparently interacting pair of CGCG 097-102 north and south. While CGCG 097-092 NED01 is peculiar it has somewhat differ redshift that CGCG 097-092 NED02. Others such as ABELL 1367:[GP82]0615 have plumes but no interacting galaxy in the area.

The oddest of the odd is what NED lists as a galaxy pair on the far left, CGCG 097-133. For the one listed as being north and the one listed as being east NED has redshifts of 680 and 660 million light-years though what exactly is the eastern member I can't determine. This is confused by NED listing the distance to the pair at 250 million light-years! The group appears to me to be at least four objects. I've attached the Sloan image of the group which also appears to be four or five objects in a group. I'd love to see what Hubble shows for this group. Unfortunately, that's apparently not happened.

If an object was not a part of the cluster and was identified only by a catalog entry that was its coordinates in the sky it is labeled by G for galaxy and Q for quasar. Otherwise its catalog name is used. I had to use a lot of lines to avoid labels from obscuring other objects.
