Arp 87 is a pair of interacting galaxies, NGC 3808A and NGC 3808B. They are situated in the Leo constellation. NGC 3808A, the brighter, is a peculiar spiral galaxy, while NGC 3808B is an irregular galaxy.
Arp 273 is a pair of interacting galaxies, 300 million light years away in the constellation Andromeda. It was first described in the Atlas of Peculiar Galaxies, compiled by Halton Arp in 1966. The larger of the spiral galaxies, known as UGC 1810, is about five times more massive than the smaller galaxy. It has a disc that is tidally distorted into a rose-like shape by the gravitational pull of the companion galaxy below it, known as UGC 1813. The smaller galaxy shows distinct signs of active star formation at its nucleus, and "it is thought that the smaller galaxy has actually passed through the larger one."
NGC 6286 is an interacting spiral galaxy located in the constellation Draco. It is designated as Sb/P in the galaxy morphological classification scheme and was discovered by the American astronomer Lewis A. Swift on 13 August 1885. NGC 6286 is located at about 252 million light years away from Earth. NGC 6286 and NGC 6285 form a pair of interacting galaxies, with tidal distortions, categorized as Arp 293 in the Arp Atlas of Peculiar Galaxies.
Arp 7 is a spiral galaxy in the constellation Hydra. Redshift-independent measurements of its distance vary widely, from 5.9 Mpc to 83.7 Mpc. Its morphological classification is SB(rs)bc, meaning it is a barred spiral galaxy with some ring-like structure.
NGC 2857 is a spiral galaxy in the constellation Ursa Major. It was discovered on January 9, 1856, by R. J. Mitchell.
UGC 8335 is a pair of strongly interacting spiral galaxies. They have been distorted by extreme tidal forces, creating prominent tidal tails and a bridge of gas and stars between the galaxies.
NGC 341 is a spiral galaxy in the constellation Cetus. It was discovered on October 21, 1881 by Édouard Stephan. It was described by Dreyer as "faint, pretty large, round, a little brighter middle, mottled but not resolved." It has a companion galaxy, PGC 3627, which is sometimes called NGC 341B. For this, reason, it has been included in Halton Arp's Atlas of Peculiar Galaxies.
NGC 507, also known as Arp 229, CGCG 502-67, MCG 5-4-44, PGC 5098, UGC 938, and V V 207, is a lenticular galaxy in the constellation Pisces. It was described as being "very faint", "pretty large", "round", "brighter in the middle", and "south of NGC 508" by John Dreyer in the New General Catalogue. The two galaxies are a part of the Atlas of Peculiar Galaxies, where NGC 507 is described as "Circular or near circular rings of small density difference."
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.
Arp 146 are a pair of interacting galaxies located 1.05 billion light-years away from Earth in the Cetus constellation. According to a study, one galaxy appears to have passed through another, leaving behind a ring formed from the bridge material and remnants of the nucleus. Under the Atlas of Peculiar Galaxies created by Halton Arp, they are categorized under galaxies that have associated rings.
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.
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.
IC 4462 is an elliptical galaxy located in the Boötes constellation. It is located 417 million light-years away from the solar system and was found by Stephane Javelle on June 22, 1895 the same day he discovered IC 4461, a spiral galaxy. It is gravitationally interacting with IC 4461 and possibly might merge with the latter in the future. Both galaxies form Arp 95, which they are classified under galaxies that have elliptical companions. Sometimes the galaxy is confused with IC 4461.
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 experiencing a gravitational tug-of-war due to the fact they are violently crashing into each other. All three galaxies are showing signs of distortion with stars and gas are being pulled away by force and stretched across different directions. Eventually, they will merge to form one giant elliptical galaxy.
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 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.
