India's upgraded Giant Metrewave Radio Telescope (uGMRT), nestled near Narayangaon in Pune district, has emerged as a pivotal instrument in unraveling the mysteries of the universe. This colossal radio telescope, one of the world's six large telescopes, has recently contributed to groundbreaking research on cosmic vibrations.

The Cosmic Symphony

Ultra-low frequency gravitational waves, akin to the bass sections in a cosmic symphony, ripple through the fabric of spacetime. These waves are anticipated to originate from colossal black hole pairs, each several million times heavier than our Sun. The relentless vibrations they induce provide a unique window into the universe's hidden harmonies.

Collaborative Efforts

Scientists from the Indian Pulsar Timing Array (InPTA) joined forces with their European and Japanese counterparts to analyze pulsar data collected over 25 years. The InPTA harnessed the unique capabilities of the uGMRT, which underwent significant upgrades in 2019, to capture sensitive radio frequency signals.


The team's findings represent a crucial milestone in gravitational wave astronomy. These tantalizing results bring us closer to detecting nano-hertz gravitational waves, expanding our understanding of the cosmos. Early career researchers and undergraduate students have played an integral role in this scientific endeavor.


As we listen to the cosmic gravitational-wave-symphony, the uGMRT stands as a testament to India's commitment to unraveling the universe's deepest secrets.
