NGC 3726is abarredspiral galaxylocated in the constellationUrsa Major.It is located at a distance of circa 45 millionlight yearsfrom Earth, which, given its apparent dimensions, means that NGC 3726 is about 85,000 light years across. It was discovered byWilliam Herschelon February 5, 1788.[2]
Structure
[edit]NGC 3726 is a spiral galaxy with a smallbar,seen with medium inclination.[3]The bar is 1.38 arcseconds across and it ends at an inner ring with 1.50 arcseconds diameter.[4]The bluest regions of star formation are located at the ring.[5]
Three arms emanate from the ring. The southern is the brightest and the north is the best defined. The third arm emanates from the east side of the ring, moves towards NNW and then bends sharply to the southwest.[6]Thespiral armsare thick and well defined and can be traced for half a revolution. The arms then branch into fragments. The spiral pattern of the galaxy is a bit disturbed[7]and asymmetrical.[6]Numerous brightHII regionsare present in the galaxy.[7]The galaxy has a massivedark matterhalo.[5]
The nucleus of the galaxy hosts asupermassive black holewith mass 106.5(3 million)M☉,based onKsbulge luminosity.[8]
Nearby galaxies
[edit]NGC 3726 belongs in theNGC 3877group,[9]which is part of the southUrsa Major groups,part of theVirgo Supercluster.[10]Other galaxies in the same group areNGC 3893,NGC 3896,NGC 3906,NGC 3928,NGC 3949,NGC 3985,andNGC 4010.[9]It may be also kinematically related with the smaller galaxiesNGC 3769andNGC 3782,located at angular distances 68' and 69' respectively.[7]
