Hickson Compact Group (HCG) 44 or Leo Quadruplet

Hickson Compact Group 44 (HCG44, or Leo quadruplet) is a group of galaxies in the constellation of Leo. It is composed by three spiral galaxies, the hedge-on NGC 3190 with its prominent dust lanes, the S-shaped NGC 3187 and NGC 3185 bar structure with an outer ring resembling the Greek letter Θ, and the bright elliptical galaxy (NGC 3193). NGC 3190, NGC 3187 and NGC 3193 have been grouped by Arp in his Atlas of Peculiar Galaxies as ARP 316.
The galaxies in HCG 44 are generally considered as a group of galaxies gravitationally bound as they lie relatively close together, at a distance (measured with the red shift method) between 56 million LY (NGC 3185) and 73 million LY (NGC 3187) from us (source: kosmoved.ru). Two dwarf spiral galaxies also appear in the image, PGC 86788/LEDA 86788 (bottom right) at around 100 million LY and PGC 2806871/LEDA 2806871 (left of center) at around 250 million LY from the Milky Way (source https: //cds.unistra.fr).

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.
