NGC 326 is a dumbbell galaxy in the constellation Pisces. It was discovered on August 24, 1865 by Heinrich d'Arrest. It was described by Dreyer as "faint, a little extended, 9th or 10th magnitude star to southeast."{{cite web|title=New General Catalog Objects: NGC 300 - 349|url=http://cseligman.com/text/atlas/ngc3.htm#326|publisher=Cseligman|access-date=October 30, 2016}}
Background
X-shaped (or "winged") radio galaxies are a class of extragalactic radio source that exhibit two, low-surface-brightness radio lobes (the "wings") oriented at an angle to the active, or high-surface-brightness, lobes. Both sets of lobes pass symmetrically through the center of the elliptical galaxy that is the source of the lobes, giving the radio galaxy an X-shaped morphology as seen on radio maps.{{cite web|title=Study of X-Shaped Radio Galaxy NGC 326 Shows Outburst History and Active Galactic Nucleus Feedback|url=http://scitechdaily.com/study-of-x-shaped-radio-galaxy-ngc-326-shows-outburst-history-and-active-galactic-nucleus-feedback/|publisher=Scitechdaily|date=February 6, 2012|access-date=October 30, 2016}}
Study of the galaxy
NGC 326 is a radio galaxy; in fact, it is one of the most prominent X-shaped galaxies ever observed. Several studies have been conducted to try to explain its morphology through either fluid motion or reorientation of the jet axis. The Chandra X-ray Observatory examined the emissions of the galaxy. The study revealed several features, including a high-temperature front that might indicate a shock, high-temperate knots around the rim of the radio emission, and a cavity associated with the eastern wing.{{Cite journal|title=A Chandra Study of the Radio Galaxy NGC 326: Wings, Outburst History, and AGN Feedback|journal=The Astrophysical Journal|volume=746|issue=2|pages=167|arxiv=1112.2707|date=December 12, 2011|last1=Hodges-Kluck|first1=Edmund|last2=Reynolds|first2=Christopher S|doi=10.1088/0004-637X/746/2/167|bibcode=2012ApJ...746..167H|s2cid=119162407}}
