Object name: NGC2744
Designation(s): NGC2744, NGC2747, NGC2749, NGC2752,
NGC 2744 is the strange galaxy in the NGC 2749 galaxy group which is located in Cancer the crab. It certainly is a train wreck of a galaxy. It is often considered a double galaxy. The southern part is also known as LEDA 200248. Is it a separate galaxy or part of the mess that is NGC 2744? Seligman considers it the latter. It is obvious something collided with what was a normal spiral galaxy. Is the southern piece the offending galaxy. If not what happened to the colliding galaxy? I find no other candidates. The north going plume may be stars ripped from the colliding galaxy and the southern blob what is left of it -- or not. I find no studies of star rotation in the main galaxy. If it has digested the colliding galaxy it should show in a study of the motion of the disk stars. But I find this one has been mostly ignored since 1985 with most papers only discussing its visual appearance and debating if the southern part is a companion or not. Until more to the contrary, I vote that the southern blob is likely the remains of a colliding galaxy. I say this as to my eye the north plume passes behind the northern galaxy then reappears below it much brighter and joins the lower blob. If so that shows the lower blob to be the most likely source of the plume, probably showing its path to the train wreck. In any case, it will eventually become part of the galaxy which will likely retain its spiral nature. Like many of the NGC galaxies, it was discovered by William Herschel on March 21, 1784. It isn't in either of the H400 observing programs.
