NGC 7436 Galaxy Group

This object is a galaxy group located over 300 million light years away in the constellation of Pegasus at a declination of +26 degrees. The image spans 20 arc-minutes in our apparent view, which corresponds to an actual width of almost 2 million light years.

This group is catalogued as Holmberg 800, although a search brings up very little information on the Holmberg catalog. This group is part of the Abell 2513 galaxy cluster.

At the center is the brightest galaxy in the image, the elliptical galaxy NGC 7436. Immediately behind this galaxy is the small spiral galaxy MCG+04-54-005, whose structure is intact and which does not appear to be interacting with 7436. Just above are 3 more NGC galaxies - 7431, 7433, and 7435. Based on the extended star streams, it looks to me as if 7436 and 7435 are interacting. The absence of blue color from these galaxies suggests that star formation is not significant and that any interaction is relatively minor.

The larger galaxy on the right side of the image is UGC 12274. Many other galaxies are also seen in the background. In my opinion, based on their colors and structure, most of these galaxies are just optically aligned and not as close together as they may seem.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
