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
