"The Arp Atlas of Peculiar Galaxies", Hardcover Book by Kanipe/Webb
The Arp Atlas of Peculiar Galaxies.... A Chronicle and Observer's Guide In 1966, astronomer Halton Arp compiled his Atlas of Peculiar Galaxies, which featured 338 images of some of the strangest looking galaxies and galaxy groups then known to exist. The purpose of the Atlas, Arp stated in his preface, was to graphically present structural peculiarities in galaxies "in order to build a realistic picture of what galaxies are really like." At the time, astronomers were struggling to formulate a workable taxonomy of "symmetrical" galaxies using classification schemes such as Edwin Hubble's tuning fork diagram. But the Atlas was comprised of the "Elephant Men" of galaxies, and their deformations challenged and defied astronomers' attempts at galaxy classification. Although the Atlas itself has been long out of print, this book not only reproduces all 338 of the original Atlas of Peculiar Galaxiesimages, including Arp's preface, it also presents new images of all Arp galaxies taken by amateur astronomers, along with finder charts and observing notes. In addition, it provides a chronicle of Arp's saga, from his early work at Mount Wilson and Palomar, where the original Atlas was assembled, to his controversial research on discordant redshifts. Although Arp's astrophysical interpretations have sparked controversy among his peers - the giants of professional astronomy - history has stoked the interests of amateur astronomers th
