Abstract
The Indian Pulsar Timing Array is an experiment aimed at detection of Gravitational waves (GWs) in the sub-microHertz frequency range by observing an ensemble of millisecond pulsars (MSPs). GWs from both the stochastic GW background as well as the individual sources like supermassive black hole binaries (SMBHBs) leave an imprint on the time-of-arrival (TOA) of the pulsed emission from MSPs, which could be detected with high precision due to the clock-like stability of these pulsars. InPTA aims to contribute its data and its analysis results to an international effort, called the International Pulsar Timing Array (IPTA), where three other experiments also contribute data.
