Gravitational waves

Astrophysicist Debarati Chatterjee, a leader in gravitational wave research, champions making science accessible. She highlights the extreme conditions of neutron stars as natural physics labs. Chatterjee's passion for outreach, honed by early life experiences and professional training, aims to inspire the next generation of women in STEM, emphasizing diversity's crucial role in scientific advancement.

The Advanced LIGO team has announced the direct detection of Gravitational waves, a major milestone in the history of science that confirms one of Einstein’s predictions and opens a new window into the near and far Universe on Thursday.

"Immensely proud that Indian scientists played an important role in this challenging quest," PM Modi tweeted as soon as the great discovery was announced by scientists.

The Laser Interferometer Gravitational-wave Observatory (LIGO), on Thursday said it has made another (third) successful detection of Gravitational waves, ripples in space and time, from the merger of two massive black holes that happened three billion light years away, on January 4, 2017.

The landmark discovery of the first direct evidence of Gravitational waves or ripples in space-time, which Albert Einstein predicted a century ago, will enable mankind to listen to the stars, and not just see them, scientists say.

A Vadodara-born astrophysicist, who was a part of a detection team of the project to ascertain the existence of Gravitational waves, has said that India should set up a third LIGO detector.

It is like an attempt to decipher a whisper in a room full of loud conversation. In a similar manner, two Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US made history in September 2015 when they detected very weak Gravitational waves, thereby proving Einstein’s model of universe right.

Gravitational waves — ripples in the fabric of spacetime — leave behind plenty of "memories" that could help detect them even after they have passed, according to a study. These waves, first detected in 2016, offer a new window on the universe, with the potential to tell us about everything from the time following the Big Bang to more recent events in galaxy centres.

A four-day gravitational wave physics and astronomy workshop (GWPAW) got underway at the Inter University Centre for Astronomy and Astrophysics (IUCAA) on Tuesday.

Indian groups contributed significantly to the historic search for Gravitational waves.

On February 11, 2016, scientists announced that they had detected 'Gravitational waves', something that people had been looking for a century since Albert Einstein first suggested that they should exist, back in 1916. The scientists had recorded a blip or a 'chirp' (like a bird's sound) from gravity waves that started 1.3 billion years ago when two black holes collided and merged into one.

Scientists have discovered new technology that may identify Gravitational waves throughout "the observable universe", instead of detecting them a billion light years away. The breakthrough could eventually see hundreds of gravity wave "events" being recorded every day.

Indian scientists played a crucial role, including in data analysis, in the path-breaking project for the detection of Gravitational waves, or ripples in space-time, which Albert Einstein predicted a century ago.

Scientists (including Indians) working with the Laser Interferometer Gravitational-wave Observatory (LIGO), on Wednesday said that they successfully detected on August 14 the fourth gravitational wave, ripples in space and time, from the merger of two massive black holes.

As many as 37 Indian scientists from nine institutes, including Inter-University Centre for Astronomy and Astrophysics, were co-authors of the Gravitational waves discovery paper — awarded the Nobel prize in Physics on Tuesday.

A year after the breakthrough detection of Einstein’s Gravitational waves in deep space through the Advanced Laser Interferometer Gravitational Wave Observatory (LIGO) experiment, Prof Archana Pai of Indian Institute of Science Education and Research (IISER) who served as part of a global team of scientists looks forward with the Indian government proposal to set up a LIGO detector in the country.

The government on Wednesday gave an “in-principle approval” for establishing a state-of-the-art Laser Interferometer Gravitational-wave Observatory (LIGO) project in the country which will bring opportunities for scientists to dig deeper into the realm of gravitation wave.

New Delhi, May 8 () The government is mulling setting up a LIGO project to study the Gravitational waves either in Rajasthan or Maharashtra. "Deliberations are on to select a site. We have shortlisted a place near Udaipur in Rajasthan and another place in Maharashtra.

Gravitational waves in space-time captured by space detectors could soon be used to discover when and how the universe's largest black holes were born. Current theories suggest that the seeds of these black holes were the result of either the growth and collapse of the first generation of stars.

The North American Nanohertz Observatory for Gravitational waves, while announcing the compelling evidence of Gravitational waves background two days ago, gave much credit to the upgraded Giant Metrewave Radio Telescope (uGMRT) near Pune and the Indian team behind it.
