NGC 5965 is aspiral galaxy located in the constellationDraco. It is located at a distance of circa 150 millionlight years from Earth, which, given its apparent dimensions, means that NGC 5965 is about 260,000 light years across. It was discovered byWilliam Herschel on May 5, 1788.[3]
Twosupernovae have been observed in NGC 5965: SN 2001cm (type II, mag. 17.5) and SN 2018cyg (type II, mag. 17).[4][5]
NGC 5965 is seen nearly edge-on, with an inclination of 80 degrees. Dust is seen across the galactic disk, while there is also a red dust lane at the nucleus.[6] The bulge is X-shaped, that suggests that the galaxy is actuallybarred.[7] NGC 5965 along with another edge-on galaxy,NGC 5746, were the galaxies used to confirm that peanut shaped bulges are associated with the presence of a bar, byspectrographically observing the disturbance caused at the velocity distributions of the galaxies.[8][9] The galaxy features some level of disk disturbance, like a warp, as the outer part of the disk along with a ring-like dust lane appear to be on a different plane from the bulge, but it could also be a projection effect.[10][11] When observed in theK band, the galaxy features a stellar ring.[11]
NGC 5965 lies in a galaxy filament which also includesNGC 5987 and its loose group,[12] which includesNGC 5981,NGC 5982,NGC 5985, three galaxies known as the Sampler.[13]
