NGC 5774 is anintermediate spiral galaxy approximately71 millionlight-years away from Earth in theconstellation ofVirgo.[1] It was discovered by Irish engineerBindon Stoney on April 26, 1851.[3]
NGC 5774 belongs to theNGC 5775 Group of galaxies—together with nearbyNGC 5775,IC 1070, and others—which is part of theVirgo III Groups strung out to the east of theVirgo 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 lowstar forming galaxy with fiveX-ray sources plus threeultraluminous X-ray source candidates.[8]
NGC 5774 is interacting with the nearby spiral galaxyNGC 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 amerger.[6]
