Halton Arp

Halton Christian "Chip" Arp (March 21, 1927 – December 28, 2013) was an American astronomer. He is remembered for his 1966 book ''Atlas of Peculiar Galaxies'', which catalogued unusual-looking galaxies and presented their images.

Arp was also known as a critic of the Big Bang theory and for advocating a non-standard cosmology incorporating intrinsic redshift. Arp developed those views in a book, ''Seeing Red: Redshift, Cosmology and Academic Science'', in 1998. Provided by Wikipedia
