Astrophysics Seminar

An international team of astronomers from India, Japan and Europe have recently published the results from monitoring pulsars, nature's best clocks, using six of the World's most sensitive radio telescopes, including the 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, millions of times heavier than our Sun. The team's results are a crucial milestone in opening a new, astrophysically-rich window in the gravitational wave spectrum. In this talk/discussion session, I shall present the basic ideas behind this Galaxy scale detector experiment, highlighting the recent findings and prospects.
