Context-

 India is first Asian country to join International pulsar timing array with upgraded Giant metrewave radio telescope

 key highlights

•  India has become the first Asian country to be a full member of IPTA consortium
• From India Observations were made by Pune based upgraded giant meter wave radio telescope
• This telescope is operated by Tata Institute of Fundamental Research – National Centre for radio Astrophysics

 International Pulsar Timing Array

• Its goal is to detect and characterize the low frequency gravitational wave universe through timing a global array of  approximately 100 milliseconds Pulsar using the largest radio telescope in the world
•  These waves are especially those which are emerging from to orbiting very large  supermassive black holes
•  sharing of resources will help to reach other IPTA goals like stabilizing a Pulsar based reference Time Scale 

Significance

 In 2016 short period gravitational waves were first detected using two  laser interferometer gravitational-wave observatory located in US
