IC 4271 is a spiral galaxy located some 800 million light-years away in the Canes Venatici constellation. [1] It is 130,000 light-years in diameter. [2] IC 4271 was first located on July 10, 1896, by Stephane Javelle, a French astronomer. [2] 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. [3] [4] IC 4271 appears to be interacting with its smaller neighboring galaxy, PGC 3096774. [2] [5]
Both galaxies form Arp 40. [6] [7] In the Atlas of Peculiar Galaxies created by Halton Arp, they fall under spiral galaxies that have companions with low-surface-brightness.
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.
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 5395 is an interacting spiral galaxy located at a distance of 160 million light years, but receding away from the Earth at 3511 kilometers per second, in the constellation Canes Venatici. It was discovered by William Herschel on May 16, 1787. NGC 5395 and NGC 5394 are included in the Atlas of Peculiar Galaxies as Arp 84 in the category "Spiral galaxies with large high surface brightness companions".
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.
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 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.
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.
IC 3441 is a type ES-0 lenticular galaxy with a bar located 880 million light-years away from the solar system in the constellation of Coma Berenices. IC 3441 was discovered on March 23, 1903, by the astronomer Max Wolf and it does not have an active galactic nucleus or an indication of star formation.
NGC 5008 is a massive barred spiral galaxy located in the Boötes constellation.
IC 3246 known as PGC 40202, is a barred spiral galaxy with a ring located in the Virgo constellation. It is situated 1.13 billion light-years away from the Solar System and was discovered by Friedrich Karl Arnold Schwassmann on September 14, 1900. IC 3246 has a surface brightness of 23.6 magnitude/arc seconds and located at right ascension and declination respectively.
IC 3786 is a type Sbc spiral galaxy in the Canes Venatici constellation. It is located 755 million light-years from the Milky Way and was discovered by Max Wolf on March 21, 1903.
IC 4000 known as PGC 2152407, is a type Sbc spiral galaxy with a ring in the constellation of Canes Venatici. It is located 1.5 billion light-years away from the solar system and has an estimated diameter of 100,000 light-years which is the same length as the Milky Way. IC 4000 was discovered by Max Wolf on March 21, 1903. It has a surface brightness of 23.3 magnitude/arc seconds and located right ascension (12:59:36.62) and declination (39:35:15:90).
IC 4017 is a type Sbc spiral galaxy with a bar located in Coma Berenices. It is located 2.3 billion light-years away and was discovered on January 27, 1904, by Max Wolf. At the redshift of 0.1773, IC 4017 is the most furthest object in the Index Catalogue and is said to be possibly interacting with its companion.
IC 1166 are a pair of galaxies in the Corona Borealis constellation comprising IC 1166 NED01 and IC 1166 NED02. They are located 977 million light-years from the solar system and were discovered on July 28, 1892, by Stephane Javelle.
