NGC 7079is abarred lenticular galaxy[2]located about 110.58 millionlight-yearsaway[3]in theconstellationofGrus.[4][5]NGC 7079 is also classified as aLINERgalaxy.[3][5]It is tilted about 51° to the Earth's line of sight.[2]NGC 7079 was discovered by astronomerJohn Herschelon September 6, 1834.[4]
Physical characteristics
[edit]NGC 7079 has a faint cigar-shaped bar withansaeat the ends, and there is another very faint spiral structure surrounding it.[6][7]The rim of the disk also has a somewhat faint ring-like structure.[7]
Emission of doubly ionized oxygen gas
[edit]In NGC 7079, it has been indicated that there is a faint emission ofdoubly ionized oxygen.Theionizedgas is rotating in the opposite direction of the stars in the galaxy. The counter-rotation has been attributed to the accretion of gas from outside of the galaxy.[2]
Group membership
[edit]NGC 7079 is a member of theNGC 7079 Group.The group, along with other nearby groups are part of the Pavo-Indus and Grus clouds of galaxies which form a connection between thePavo–IndusandVirgo Superclusters.The other members of the NGC 7079 Group areNGC 7070,NGC 7070A,NGC 7097,NGC 7097A,ESO 287-37,ESO 287-39,ESO 287-41,andESO 287-43.[8]
