IRAS 14348-1447 known as PGC 52270, are a pair of spiral galaxies located 1 billion light-years away in the constellation of Libra.[1][2] The galaxy IRAS 14348-1447NE, is in the early process of merging with IRAS 14348-1447SW, causing gravity to pull stars from both galaxies and forming tidal tails.[3] As the interaction takes place, molecular gas is swirled about and creating emission that is responsible for the galaxies' ultraluminous appearance.[3][4][5]
According to SIMBAD, IRAS 14348-1447, is a Seyfert 1 galaxy and has an active galactic nucleus, indicating certain activity in its supermassive black hole has awakened, possibly turning it into a quasar.[2][4]
