NGC 7603 is a spiral Seyfert galaxy in the constellation Pisces. [1] It is listed (as Arp 92) in the Atlas of Peculiar Galaxies. [4] It is interacting with the smaller elliptical galaxy PGC 71041 nearby. [1]
This galaxy pair has long been a cornerstone for those who are critical of the view that the universe is expanding, and advocates for non-standard cosmology such as Halton Arp, Fred Hoyle, and others.[ like whom?] [5] [6] This is due to the position of two quasars, one at each edge of the filament connecting the two galaxies, with much more redshift than either galaxy.
