OH gigamaser emission has been detected in the luminous FIR galaxy IRAS 14070+0525 at a redshift of 0.265. The FIR luminosity of IRAS 14070+0525 is 1012.5 L. The OH line luminosity is 1.4 × 104 L, making it the most luminous known OH emitter. The OH line emission covers a velocity range of approximately 2400 km s-1. Two distinct components in the OH emission reveal a powerful outflow component and/or the interactive nature of the system.
