IC 1015 (Gary Imm)

Celestial hemisphere: Northern · Constellation: Boötes (Boo) · Contains: IC 1015 · PGC 1481336 · PGC 1481360 · PGC 1482595 · PGC 1483980 · PGC 2800988

IC 1015

This Astrobin Debut Object is a merging galaxy trio located 0.8 billion light years away in the constellation of Bootes at a declination of +15 degrees. It is a magnitude 15 object which spans 40 arc-seconds in our apparent view. This corresponds to a width of 160,000 light years.

I was hoping to find something about this object out there, but my search for information on IC 1015 only turned up images of trains.

I think I see 3 cores here, signaling a merger of a trio of small galaxies, but anything is possible. I like the curving (looping?) star stream tails. It looks a bit like NGC 1540 or Arp 63.

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.
