Famous Places - Interactions

 | 752-6-410-978-87  | 204.97,0.84 | NED | SDSS | 
ARP 240, an interacting pair of galaxies. Note, how the galaxies distorted each other.

 | 756-1-589-1246-145  | 204.061,-1.04 | NED | SDSS | 
Another pair of galaxies, undergoing a violent interaction. The brighter object is UGC 08584. This system has also been observed in the infrared, by the IRAS satellite, and has been classified as a triplet.

 | 94-3-372-830-930  | 30.551,-0.101 | NED | SDSS | 
Two spiral galaxies, NGC 799, and NGC 800. The two galaxies are very close to one another even in redshift.

 | 125-6-196-782-1232  | 18.232,0.981 | NED | SDSS | 
NGC 428, a spectacularly blue nearby spiral galaxy. The blue color is an indication of very active star formation in this galaxy.

 | 1336-4-50-291-693  | 258.287,59.327 | NED | SDSS | 
UGC 10770, a young spiral galaxy, just undergoing a collision. This object is mentioned in many catalogs of interacting galaxies (ARP, etc).

 | 94-4-99-1220-253  | 349.736,0.244 | NED | SDSS | 
NGC 7603/ PGC 07041, an interacting pair. Notice the bridge between the two galaxies. The bigger object, NGC 7603, is a well-known Seyfert galaxy. These are known for their very small and bright core.

 | 125-3-285-966-1098  | 31.566,-0.292 | NED | SDSS | 
UGC 1597, a Seyfert type galaxy with an active nucleus. Notice the disturbed appearance of the galaxy. This object may be the remnant of a collision between two galaxies. As a by-product ofthe collision, gas from one galaxy is being dumped onto a black hole at the center of the other galaxy, giving rise to the nuclear activity.

 | 94-4-533-590-1368  | 54.622,0.366 | NED | SDSS | 
The faint reddish object is a quasar at redshift z=5.0. Quasars are the most luminous objects in the Universe. They consist of a giant black hole in the center of a host galaxy. This object was the first to exceed the magic distance threshold of z=5.0.
