India’s Giant Metrewave Radio Telescope (GMRT) was among the world’s six large telescopes that played a vital role in providing evidence confirming the presence of gravitational waves using pulsar observations, said scientists on Thursday.
An international team of astronomers from India, Japan and Europe has published the results from monitoring pulsars, called ‘nature’s best clocks’, by using six of the world’s most sensitive radio telescopes, including India’s largest telescope, the Pune-based uGMRT.
“These results provide a hint of evidence for the relentless vibrations of the fabric of the universe, caused by ultra-low frequency gravitational waves. Such waves are expected to originate from a large number of dancing monster black hole pairs, crores of times heavier than our sun,” said a statement issued by the city-based National Centre for Radio Astrophysics-Tata institute of Fundamental Research (NCRA-TIFR).
