NGC 5929 is a well-studied[8]Seyfert galaxy in the constellationBoötes.[9][10] It was discovered by English astronomerJohn Herschel on May 13, 1828.[11] In the revisedNew General Catalogue it is described as "elongated, brighter toward the middle, with a slightly diffuse halo". This galaxy is located at an estimated distance of 133 millionlight-years (40.8megaparsecs).[3] It forms aninteracting pair[12] withNGC 5930 at an angular separation of0.5′; together they form entry number 90 inHalton Arp's 1966Atlas of Peculiar Galaxies.[13] A dust streak from NGC 5930 appears to lie in front of NGC 5929, suggesting that the former galaxy is the closer member of this pair.[6]
Themorphological classification of NGC 5929 is Sab,[6] indicating this is aspiral galaxy with tightly wound spiral arms. It has a Seyfert 2 nucleus with a bi-polar radio jet oriented along aposition angle of ~60°.[14] This galaxy is aradio source having a double-lobe structure, with each lobe showing an emission region counterpart in the optical band.[10][15] When observing the double-ionized oxygen line, each lobe is found to display a velocity component. The peaks of both the radio emission and velocity component are aligned.[8]
