15 Facts About Halton Arp

Halton Christian "Chip" Arp was an American astronomer.

Halton Arp is remembered for his 1966 book Atlas of Peculiar Galaxies, which catalogued unusual-looking galaxies and presented their images.

Halton Arp developed those views in a book, Seeing Red: Redshift, Cosmology and Academic Science, in 1998.

Halton Arp was married three times and has four daughters, including comic artist Andrice Arp, and five grandchildren.

Halton Arp became a research assistant at Indiana University in 1955, and then in 1957 became a staff member at Palomar Observatory, where he worked for 29 years.

Halton Arp died in Munich, Germany, on December 28,2013.

Halton Arp compiled a catalog of unusual galaxies titled Atlas of Peculiar Galaxies, which was first published in 1966.

Halton Arp later used the galaxies in the atlas as arguments for his views in the debate on quasi-stellar objects.

In 1966, Halton Arp published the Atlas of Peculiar Galaxies, which contained photographs of 338 nearby galaxies that did not fall into any of the classic categories of galaxy shapes.

Halton Arp's goal was to produce a selection that modellers could use in order to test theories of galactic formation.

In 1967 Halton Arp noted that several of these objects appeared on the list of quasars.

Halton Arp noted that quasars were not evenly spread over the sky, but tended to be more commonly found in positions of small angular separation from certain galaxies.

Halton Arp argued that the redshift was not due to Hubble expansion or physical movement of the objects, but must have a non-cosmological or "intrinsic" origin, and that quasars were local objects ejected from active galactic nuclei.

Halton Arp never wavered from his stand against the Big Bang, and until shortly before his death in 2013, he continued to publish articles stating his contrary view in both popular and scientific literature, frequently collaborating with Geoffrey Burbidge and Margaret Burbidge.

Halton Arp explained his reasons for believing that the Big Bang theory is wrong, citing his research into quasars, or quasi-stellar objects.
