NGC 3751
NGC 3751 is a type E-S0 lenticular galaxy located in the Leo constellation. It is located 450 million light-years away from the Solar System and was discovered by Ralph Copeland on April 5, 1874. To date, a non-redshift measurement gives a distance of approximately 138,000 Mpc (450 million light-years) for NGC 3751. This value is within the Hubble Distance values. Copeland Septet NGC 3751 is a member of the Copeland Septet. The other members are NGC 3745, NGC 3746, NGC 3748, NGC 3750, NGC 3753 and NGC 3754. Halton Arp noticed the 7 galaxies in which he published inside his article in 1966. This group is known as Arp 320 in which another galaxy, PGC 36010 is part of it. This group was also observed by Paul Hickson, in which he included them inside his article which was published in 1982. It is noted that this group is designated as Hickson 57.

Ralph Copeland
Ralph Copeland FRSE FRAS (3 September 1837 – 27 October 1905) was an English astronomer and the third Astronomer Royal for Scotland. Life Copeland was born at Moorside Farm, near Woodplumpton in Lancashire, England the son of Robert Copeland, yeoman, and his wife, Elizabeth Milner, and attended Kirkham Grammar School. He spent five years in Australia where he discovered his interest in astronomy. He returned in 1858 to pursue a career in engineering. Eager to pursue his astronomical interests, Copeland built a small observatory, gave up engineering, and then travelled to Germany to study astronomy at the University of Göttingen. When he returned to England, as a patron of Lord Rosse, Copeland brought back German methods of astronomy. Later he appointed many German astronomers as assistants, such as Oswald Lohse. Copeland then worked at the Dun Echt Observatory owned by the 26th Earl of Crawford. Copeland was a frequent traveler on worldwide expeditions and observed the 1 ...

NGC Objects
The ''New General Catalogue of Nebulae and Clusters of Stars'' (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the ''Index Catalogues'' (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use. The NGC expanded and consolidated the cataloguing work of William and Caroline Herschel, and John Herschel's ''General Catalogue of Nebulae and Clusters of Stars''. Objects south of the celestial equator are catalogued somewhat less thoroughly, but many were included based on observation by John Herschel or James Dunlop. The NGC contained multiple errors, but attempts to eliminate them were made by the ''Revised New General Catalogue'' (RNGC) by Jack W. Sulenti ...

Atlas Of Peculiar Galaxies
The ''Atlas of Peculiar Galaxies'' is a catalog of peculiar galaxies produced by Halton Arp in 1966. A total of 338 galaxies are presented in the atlas, which was originally published in 1966 by the California Institute of Technology. The primary goal of the catalog was to present photographs of examples of the different kinds of peculiar structures found among galaxies. (online version, including Arp's original tabular data, and PDF link) Background Arp realized that the reason why galaxies formed into spiral or elliptical shapes was not well understood. He perceived peculiar galaxies as small "experiments" that astronomers could use to understand the physical processes that distort spiral or elliptical galaxies. With this atlas, astronomers had a sample of peculiar galaxies that they could study in more detail. The atlas does not present a complete overview of every peculiar galaxy in the sky but instead provides examples of the different phenomena as observed in nearby ga ...

Galaxies
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek ' (), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a hundred million stars, to the largest galaxies known – supergiants with one hundred trillion stars, each orbiting its galaxy's center of mass. Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies. Galaxies are categorized according to their visual morphology as elliptical, spiral, or irregular. Many are thought to have supermassive black holes at their centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. As of ...

Halton Arp
Halton Christian "Chip" Arp (March 21, 1927 – December 28, 2013) was an American astronomer. He was known for his 1966 ''Atlas of Peculiar Galaxies'', which (it was later theorized) catalogues many examples of interacting and merging galaxies, though Arp disputed the idea, claiming apparent associations were prime examples of ejections.Halton Arp, ''Seeing Red: Redshift, Cosmology and Academic Science'', Montreal: Aperion (1998), pp. 14, 61–62, 72, 104–105 Arp was also known as a critic of the Big Bang theory and for advocating a non-standard cosmology incorporating intrinsic redshift. Biography Arp was born on March 21, 1927, in New York City. He was married three times, has four daughters and five grandchildren. His bachelor's degree was awarded by Harvard (1949), and his PhD by Caltech (1953). Afterward he became a Fellow of the Carnegie Institution of Washington in 1953, performing research at the Mount Wilson Observatory and Palomar Observatory. Arp became a ...
