Arp 108 (Gary Imm)

Celestial hemisphere: Southern · Constellation: Eridanus (Eri)

Arp 108

This Astrobin Debut Object is located in the constellation of Eridanus at a declination of -22 degrees. In his Arp catalog, Dr. Arp classified this object into the category of Elliptical and Elliptical-like Galaxies Connected to Spirals.

The face-on spiral galaxy at the center of the image is LEDA 11493, located 0.7 billion light years away. This galaxy has been described as having 3 arms, but it looks to me like one of the two arms simply has been disturbed and elongated. This magnitude 14 galaxy spans 0.8 arc-minutes in our apparent view, which corresponds to a large diameter of 170,000 light years.

The elliptical to the lower right is LEDA 11491. This galaxy is further away, at almost 1 billion light years away. As is often the case, galaxies that Dr. Arp describes as a “companion” or “connected” in his categorizations are simply unrelated line-of-sight galaxies in the distance.

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.
