NGC 5719 is an intermediate or barred spiral galaxy located in the constellation Virgo. It is located at a distance of 94 million light years from Earth.[1] It was first discovered by William Herschel in April 1787, but also observed by John Herschel in April 1828 and by George Phillips Bond in March 1853, who catalogued the object as NGC 5658 under the New General Catalogue.[2]

The luminosity class of NGC 5719 is I-II and it has a broad HI line. Additionally, it is a narrow line active galaxy (NLAGN).[1] In far 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
editNGC 5719 is classified as an Sab galaxy found almost edge-on. It is interacting with a nearby face-on Sbc companion, NGC 5713.[4][5] The dust lane of the galaxy is tilted, as well as bent significantly and inclined to its major axis.[6]
The galaxy has two HI tidal bridges which loop around it and are connecting with NGC 5713. There is a detection of two HI tidal tails leaving NGC 5713. Inside the disk of the galaxy (NGC 5719), ionized and neutral hydrogen are present. Both are counter-rotating in respect to the main stellar disk.[4][7] When measuring the kinematics 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
edit
NGC 5719 is part of the NGC 5746 group according to A.M. Garcia. In this galaxy group there are 31 members including NGC 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 the Virgo III cluster, one of the clusters in the Virgo Supercluster.[9]
