Did LIGO really detect Gravitational Wave signals or was it just noise?

After the Laser Interferometer Gravitational-Wave Observatory (LIGO) first observed Gravitational Waves in September 2015 and then again in December 2015 and for the third time in January 2017, a team of researchers from Niels Bohr Institute in Copenhagen, Denmark, calls into question whether the LIGO observatory had actually detected the gravitational wave signals. “The detection of … Continue reading Did LIGO really detect Gravitational Wave signals or was it just noise?

LIGO: Now, gravitational waves provide clues on how binary black holes form

On January 4, 2017, the Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves — ripples in space and time — for the third time. The first success in observing gravitational waves was in September 2015 and the second detection was in December 2015. While the September 2015 detection became important as it was the first … Continue reading LIGO: Now, gravitational waves provide clues on how binary black holes form

LIGO scientific collaboration is Physics World 2016 breakthrough of the year

Physics World announced that the 2016 Breakthrough of the Year goes to the LIGO Scientific Collaboration for “their revolutionary, first ever direct observations of gravitational waves”. LIGO stands for the Laser Interferometer Gravitational-wave Observatory. “What’s been achieved by LIGO, particularly in a relatively short space of time, is truly incredible. The observations it has made are … Continue reading LIGO scientific collaboration is Physics World 2016 breakthrough of the year

LIGO: Merger makes waves, again

A little more than three months after detecting gravitational waves from the merger of two massive black holes, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors recorded on December 26, 2015, gravitational waves from the merger of two smaller black holes nearly 1.4 billion years ago. This has confirmed that the merger of binary black holes … Continue reading LIGO: Merger makes waves, again

Editorial: LIGO-India – A landmark for Indian scientists

The Union Cabinet has finally granted in-principle approval for a gravitational wave detector in India. The clearance, awaited for five years, comes close on the heels of the detection of the elusive gravitational waves for the first time; the Laser Interferometer Gravitational-Wave Observatory (LIGO) based in Washington and Louisiana in the U.S. found evidence of gravitational waves … Continue reading Editorial: LIGO-India – A landmark for Indian scientists

Listening to the chirps of gravitational waves

A century after Albert Einstein predicted the existence of gravitational waves, after decades of hard work to detect them directly and nearly four months of rigorous scrutiny of data, an international team of scientists, which also included researchers from India, finally detected the most elusive waves stretching and compressing the fabric of space-time. The gravitational … Continue reading Listening to the chirps of gravitational waves

Editorial: Elusive gravitational waves detected

The detection of ripples in space-time, known as gravitational waves, here on Earth marks a watershed moment for astronomy and for science as a whole. The detection at once improves our understanding of the workings of the universe and, more important, throws open a big opportunity to study it from completely new angles. It opens … Continue reading Editorial: Elusive gravitational waves detected
