NGC 5719 is anintermediate orbarred spiral galaxy located in the constellationVirgo. It is located at a distance of 94 millionlight years fromEarth.[1] It was first discovered byWilliam Herschel in April 1787, but also observed byJohn Herschel in April 1828 and byGeorge Phillips Bond in March 1853, who catalogued the object as NGC 5658 under theNew General Catalogue.[2]

Theluminosity class of NGC 5719 is I-II and it has a broadHI line. Additionally, it is anarrow line active galaxy (NLAGN).[1] Infar infrared (40-400 ɥm), the luminosity of NGC 5719 is 1.70 x 1010 Lʘ (1010.23 Lʘ) while its total luminosity in infrared (from the 8-1000 ɥm range) is 2.24 x 10 Lʘ (1010.35 Lʘ).[3]

Characteristics

[edit]

NGC 5719 is classified as anSab galaxy found almost edge-on. It isinteracting with a nearby face-on Sbc companion,NGC 5713.[4][5] Thedust lane of the galaxy is tilted, as well as bent significantly and inclined to its major axis.[6]

The galaxy has two HItidal bridges which loop around it and are connecting with NGC 5713. There is a detection of two HItidal tails leaving NGC 5713. Inside the disk of the galaxy (NGC 5719),ionized andneutral hydrogen are present. Both are counter-rotating in respect to the mainstellar disk.[4][7] When measuring thekinematics of both counter-rotating stellar disks and the ionized-gas disk, they extend by about 40 arcsec (4.3 kpc) from NGC 5719's center.[7]

NGC 5746 group

NGC 5719 is part of theNGC 5746 group according to A.M. Garcia. In this galaxy group there are 31 members includingNGC 5636, NGC 5638,NGC 5668,NGC 5690,NGC 5691,NGC 5692, NGC 5701,NGC 5705, NGC 5713,NGC 5725,NGC 5740,NGC 5746,NGC 5750, IC 1022, IC 1024 and IC 1048.[8] Together the NGC 5719 group is part of theVirgo III cluster, one of the clusters in theVirgo Supercluster.[9]
