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]

Contents

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

NGC 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 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]

An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. They are one of the four main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae, along with spiral and lenticular galaxies. Elliptical (E) galaxies are, together with lenticular galaxies (S0) with their large-scale disks, and ES galaxies with their intermediate scale disks, a subset of the "early-type" galaxy population.

NGC 1427 is a low-luminosity elliptical galaxy located approximately 71 million light-years away from Earth. It was discovered by John Frederick William Herschel on November 28, 1837. It is a member of the Fornax Cluster. The galaxy has a stellar mass of 7.9 × 1010M☉, and a total mass of 9.4 × 1010M☉. However, the mass of the dark matter halo surrounding the galaxy is around 4.3 × 1012M☉.

<span class="mw-page-title-main">NGC 5713</span> Peculiar and asymmetric galaxy in the constellation Virgo

NGC 5713 is a peculiar, asymmetric galaxy in the constellation Virgo. Although classified as a spiral galaxy by most galaxy catalogs, NGC 5713 is very different from most normal spiral galaxies. While most spiral galaxies either have either two well-defined spiral arms or a filamentary spiral-like structure, this spiral galaxy has only one visible spiral arm in its disk. This makes it a galaxy of the Magellanic type. Gravitational interactions with the nearby spiral galaxy NGC 5719 may be responsible for producing the disturbed, asymmetric structure including the single spiral arm.
