NGC 5774 is an intermediate spiral galaxy approximately 71 million light-years away from Earth in the constellation of Virgo. [1] It was discovered by Irish engineer Bindon Stoney on April 26, 1851. [3]

Contents

NGC 5774 belongs to the NGC 5775 Group of galaxies—together with nearby NGC 5775, IC 1070, and others—which is part of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies. [4] [5] It has been classified as a "low surface brightness" (LSB) galaxy, but its central surface brightness is 5 times brighter than the brightest LSB galaxies. [5] [6] It has a multiple spiral pattern with bright blue knotty structure all along the arms. [7]

It is an extremely low star forming galaxy with five X-ray sources plus three ultraluminous X-ray source candidates. [8]

Interaction with NGC 5775

NGC 5774 is interacting with the nearby spiral galaxy NGC 5775 in the form of two connecting H I bridges through which the gas is travelling from NGC 5774 to NGC 5775. [5] Faint optical emission, as well as radio continuum emission, are also present along the bridges. [6] It is possible that star formation is occurring between the galaxies. [5]

This system may be in the early stages of a merger. [6]

NGC 5775 is a spiral galaxy, a member of the Virgo Cluster, that lies at a distance of about 70 million light-years. Although the spiral is tilted away from us, with only a thin sliver in view, such a perspective can be advantageous for astronomers. For instance, astronomers have previously used the high inclination of this spiral to study the properties of the halo of hot gas that is visible when the galaxy is observed at X-ray wavelengths. It is a member of the NGC 5775 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.

<span class="mw-page-title-main">NGC 4762</span> Lenticular galaxy in the constellation Virgo

NGC 4762 is an edge-on lenticular galaxy in the constellation Virgo. It is at a distance of 60 million light years and is a member of the Virgo Cluster. The edge-on view of this particular galaxy, originally considered to be a barred spiral galaxy, makes it difficult to determine its true shape, but it is considered that the galaxy consists of four main components — a central bulge, a bar, a thick disc and an outer ring. The galaxy's disc is asymmetric and warped, which could be explained by NGC 4762 mergering with a smaller galaxy in the past. The remains of this former companion may then have settled within NGC 4762's disc, redistributing the gas and stars and so changing the disc's morphology.
