IRAS 14348-1447 known as PGC 52270, [2] are a pair of spiral galaxies located 1 billion light-years away in the constellation of Libra. [1] [3] [4] The galaxy IRAS 14348-1447NE, [5] is in the early process of merging with IRAS 14348-1447SW, [6] 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] [7] [8]

IRAS 14348-1447, is classified a Seyfert 1 galaxy [2] and has an active galactic nucleus, indicating certain activity in its supermassive black hole has awakened, possibly turning it into a quasar. [7]
