Atlas of Peculiar Galaxies

The Atlas of Peculiar Galaxies is an astronomical catalog. It lists 338 unusual galaxies with photographs.

The Antennae Galaxy (Arp 244)

history

The catalog was compiled by Halton Arp in the 1960s and published in 1966. Therefore it is also called the Arp catalog .

Arp looked for groups of galaxies and galaxies of unusual appearance in his own work and lists of other astronomers. For example, it references elements of the Atlas and Catalog of interacting galaxies . With the 5-meter telescope of the Mount Palomar Observatory under good observation conditions, he took a photograph of each object in the blue spectral range.

Arp divided his catalog of unusual galaxies into groups according to purely morphological criteria.

meaning

The Arp catalog was the starting point for many detailed investigations of unusual and interacting galaxies, even if the specific morphological classifications and some underlying model concepts of Arp are often less important today.

Arp or APG are used as abbreviations.
