The IPTA’s Search for Nanohertz Gravitational Waves

Detection of the radio emission from the astronomical object in 1930+ by Karl Jansky started an era of Radio Astronomy followed by many discoveries enriching our understanding of the Universe we live in. Similarly, we are on the verge of opening a new window (ultra-low frequencies) in Gravitational Wave Astronomy. We are watching the rolling history of scientific discoveries in slow motion.
