Hello!

per Wikipedia: Interacting galaxies (colliding galaxies) are galaxies whose gravitational fields result in a disturbance of one another. An example of a minor interaction is a satellite galaxy's disturbing the primary galaxy's spiral arms. The satellite's gravity could attract one of the primary's spiral arms. Or the satellite could dive in to the primary, disrupting it.
An example of a major interaction is a galactic collision of two large galaxies. Because of the tenuous distribution of matter in most galaxies, these collisions are not like a head-on car wreak, but more of a gravitational interaction.


American astrophysicist Halton Arp, (1927 - 2013), graduated from Harvard University in 1949 and received his doctorate from Caltech in 1953. In 1957, he became a staff member at Palomar Observatory, and worked there for 29 years. Later, In 1983 he went on to join the staff of the Max Planck Institute for Astrophysics near Munich, Germany.
While at Caltech, he began 'collecting' unusual galaxies that other researchers would drop from their studies as being too unusual or peculiar. Arp realized that these odd galaxies represented different stages in galaxy evolution, and devoted his career to studying them and related quasi-stellar objects (QSOs), utilizing the 200-inch Hale telescope.
This eventually led to his challenging the current interpretation of some of these highly redshifted sources, even calling into question the Big Bang theory. Until his death in 2013, Arp continued to hold his contrary view and published his research in both popular and scientific literature. Today, with modern observatory cameras and space telescopes available, conclusive research has proven Arp's "counter-theories" of intrinsic redshift to be incorrect. But, even though he was eventually proven to be wrong, Halton Arp made significant contributions to astrophysics by his strong challenges to accepted theory, forcing other astronomers to re-validate their assumptions about galaxy formation and cosmology.
Arp's atlas also has become a useful tool for the advanced amateur astronomer looking for deep-sky observing/imaging projects.
The amateur astronomer will find many of the 'Arp' objects listed on star atlas's and observing guides as NGC, IC, and UGC galaxies.

         

Arp compiled a catalog of unusual galaxies titled Atlas of Peculiar Galaxies, which was first published in 1966 which contained photographs of 338 nearby galaxies that did not fall into any of the classic categories of galaxy shapes. Arp's atlas is recognized now as an excellent compilation of interacting and merging galaxies.

In 2006 Amatuer Astronomers Jeff Kanipe and Dennis Webb expanded Arp's atlas into an observers guide, complete with Arp's original images, along with finder charts and CCD images and visual observations from other participating amateurs.
It's a great book to use in the field!!



Additionally, there's several great online resources.
Amateur astronomer Bob Hill of the Amarillo Astronomy Club, has put together a great site of his observations on the 100 best Arp Galaxies by season. You can find the first installment here: Touring the Peculiar Universe:

Scottish amateur David Richards has a very good site of the ARP's visible from his home observatory: David's Astronomy Pages - ARP Peculiar Galaxies:

Also, amateur Alvin Huey has a good observing book on his website that you can purchase.
(he also has a number of free downloads too!) faintfuzzies:

Finally, you can find a PDF of Dr. Halton Arp's atlas online here at: ATLAS OF PECULIAR GALAXIES:

Below is my personal observation list of the 'Arp Atlas of Peculiar Galaxies'.

I currently have 145 out of 338 objects visible from my Pittsburgh, PA latitude of around +40.
Around half of my images were taken using a StellaCam-3 peltier-cooled deepsky video camera. The rest was using a ZWO ASI294MC camera. Each image has minimal processing applied to it: brightness/contrast adjusted, image rotated to match that of the Arp Atlas book, and resized to have the same general field size across images. I then made a negative 'finder chart' with a red line indicating the general location of the peculiarity.
