NGC 6040 is interacting with the lenticular galaxy PGC 56942. As a result of this interaction, NGC 6040's southern spiral arm has been warped in the direction toward PGC 56942. NGC 6040 and PGC 56942 are both members of the Hercules Cluster.
IC 4271 is a spiral galaxy located some 800 million light-years away in Canes Venatici constellation. It is 130,000 light-years in diameter. IC 4271 was first located on July 10th 1896 by Stephane Javelle, a French astronomer. It hosts a Seyfert type 2 nucleus, containing an acceleration disc around its supermassive black hole which releases large amounts of radiation, hence its bright appearance. IC 4271 appears to be interacting with its smaller neighboring galaxy, PGC 3096774.
UGC 717 is a barred spiral galaxy located in Pisces. The galaxy is located 520 million light-years away from the solar system. It is designated as Arp 11 in the Atlas of Peculiar Galaxies which was produced by Halton Arp. UGC 717 falls under the category of spirals that have split-arms. It is known to have a LINER active galactic nucleus according to SIMBAD.
PGC 4789 is a distant barred spiral galaxy in the Pisces constellation. It is located 675 million light-years from the Milky Way and seems to be interacting with its neighboring galaxies. it is known as Arp 48 in the Atlas of Peculiar Galaxies catalogue. In this class, PGC 4789 falls into galaxies that have at least one low surface brightness companion.
UGC 934, known as PGC 5085, is a large spiral galaxy about 470 million light-years away from the solar system. It is located in the constellation of Pisces and about 285,000 thousand light-years in diameter. With its neighboring galaxy PGC 212740, they together form Arp 70, the 70th number in the Atlas of Peculiar Galaxies which was created by Halton Arp. In this class, they fall under spiral galaxies that have a small high-surface brightness companions.
IC 4461 is a spiral galaxy located in the Boötes constellation, located at distance of 417 million light-years from both the Milky Way and Andromeda Galaxy.
UGC 4457 known as PGC 23935, is a barred spiral galaxy, containing an active galactic nucleus in the Cancer constellation. It is located 500 million light-years away from the solar system and has a diameter of 290,000 light-years, making it slightly more massive compared to the Milky Way. The galaxy is moving away at a speed of 11,162 kilometers per second.
UGC 4881 is a pair of interacting galaxies, UGC 4881A and UGC 4881B. They are located in the constellation Lynx, some 500 million light-years away. UGC 4881, the brighter, is a peculiar spiral galaxy. It has been heavily documented by the Hubble Space Telescope, and is cataloged in the Atlas of Peculiar Galaxies.
UGC 4653 known as Arp 195, is a trio of interacting galaxies located 763 million light-years away from the solar system in the Lynx constellation. The galaxies are being distorted through gravitational interactions with each other.
NGC 7393 is a barred spiral galaxy in the constellation Aquarius. It is estimated to about 120 million light-years from the Milky Way and about 70,000 light-years in diameter. NGC 7393 belongs to the class of spiral galaxies with separated sections in the Arp catalog. Astronomer Halton Arp divided his catalog of unusual galaxies into groups based on purely morphological criteria. NGC 7393 was discovered by astronomer William Herschel on October 5, 1785.
Arp 251 is a group of three spiral galaxies. The galaxies are visible in the constellation Cetus. Arp 251 is cataloged in the Atlas of Peculiar Galaxies, which is a catalog of unusual galaxies put into groups based on purely morphological criteria. Arp 251 belongs to the class of galaxies with signs of splitting.
UGC 1840 known as Arp 145, are a pair of interacting galaxies located 250 million light-years away from the solar system in the Andromeda constellation. Made up of two galaxies, UGC 1840 NED01 and UGC 1840 NED02, the two galaxies had recently collided with each other in which the elliptical galaxy has penetrated through the spiral galaxy's nucleus leaving a hole in its middle, thus forming a ring galaxy. With a diameter of 1.3 arc minutes, close to 100,000 thousand light-years, they are roughly the same size as the Milky Way.
UGC 224 known as Arp 201, are pair of interacting galaxies located 860 million light-years in the constellation of Pisces.
UGC 2812 known as Arp 219, are pair of interacting galaxies located 470 million light-years away in the Eridanus constellation. Both galaxies appeared to be distorted and tangled with each other which suggests their inevitable merging to form an elliptical galaxy. Both objects are part of Atlas of Peculiar galaxies, where they are categorized under galaxies that have adjacent loops which are a manifestation of structures that were formed by gravitational interactions.
NGC 5279 is a spiral galaxy in the constellation Ursa Major. It was discovered by German-British astronomer William Herschel in 1789. NGC 5279 is in gravitational interaction with the galaxy NGC 5278. This pair of galaxies appears in Halton Arp's Atlas of Peculiar Galaxies under the designation Arp 239. The luminosity class of NGC 5279 is I1. NGC 5279 is a galaxy whose core shines in the ultraviolet region. It is listed in the Markarian catalog under the designation Mrk 271.
PGC 1470080 is a type E elliptical galaxy located in the Boötes constellation. It is located 3 billion light-years away from the solar system and has a diameter of 571,000 thousand light-years, making it a Type-cD galaxy and one of the largest.
IC 1166 are a pair of galaxies in Corona Borealis constellation comprising of IC 1166 NED01 and IC NED02. They are located 977 million light-years from the solar system and were discovered on July 28, 1892, by Stephane Javelle.
