NGC 5514 is a pair of merging disk galaxies in the northern constellation of Boötes. They were discovered by German astronomer Heinrich d'Arrest on April 26, 1865.[6] The galaxies are located at an estimated distance of 347 million light-years.[2] The morphology of the system is similar to the Antennae Galaxies, NGC 4038/NGC 4039. A distinct tail extends to the east for an angular distance of 1.5′. There is a fainter tail extending a comparable distance to the west.[3] This galaxy pair likely forms a small group with the nearby spiral galaxy NGC 5519.[4]
This appears to be a collision between two galaxies of unequal mass, having a 2:1 mass ratio. They display activity of the LINER type, but this is located in two regions in the outer parts away from the combined nucleus.[3] These may be large shock regions caused by the collision. There are two corresponding starburst regions, one of which has outflows that have created a supergiant galactic bubble.[4]
