Galaxy in the constellation Triangulum From Wikipedia, the free encyclopedia
NGC 1060 is a lenticular galaxy approximately 256 million light-years away from Earth in the constellation of Triangulum.[1] It was discovered by William Herschel on September 12, 1784.[3]

NGC 1060 is the brightest member of the galaxy group LGG 72, which contains approximately 15 galaxies.[4][5] Intergalactic medium (IGM) in this system is highly disturbed, with separate X-ray peaks centred on the two main galaxies of the group, NGC 1060 and NGC 1066.[4] A ~250 kpc arc of hot gas is linking these two galaxies.[4] The system appears to be undergoing a merger, which may have triggered the nuclear activity in NGC 1060.[4][5]
In 2013 a small-scale (20”/7.4 kpc) jet source was detected in NGC 1060, indicating a remnant of an old, low power outburst.[4] The radio emission which arises from this jet was also detected.[6][5]
NGC 1060 is an active galaxy, with confirmed active galactic nucleus (AGN).[6]
Supernova SN 2004fd of magnitude 15.70 was detected in NGC 1060 on October 22, 2004.[7] It was discovered by Tom Boles who was using 0.35m Schmidt-Cassegrain telescope during searches for the UK Nova/Supernova Patrol.[7] The supernova was classified as type Ia, and was located very close to the nucleus of its host galaxy (the J2000 epoch celestial coordinates: RA 02h 43m 15.20s, Dec +32° 25′ 26.00″).[8][1]
