Pune: Scientists worldwide have discovered gravitational waves and light coming from the collision of two neutron stars. Scientists were also able to detect light, which is electronic magnetic waves. This was revealed at a press conference on Monday.

Indian scientists also participated in the detection. Scientists say this detection proves that heavy metals like gold and platinum are produced through the collision of two neutron stars. The study of gravitational waves is like an insight for understanding the nature of the cosmos and the most violent events in the history of the universe.

In this detection, several Indian telescopes such as AstroSat, Giant Metrewave Radio Telescope (GMRT) and the Himalayan Chandra Telescope (HCT) participated in the search for electromagnetic flashes.

August 17 this year saw a major breakthrough in astronomy when gravitational waves from a pair of colliding neutron stars were detected for the first time by the US-based Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Europe-based Virgo detector. Dibankar Bhattacharya, one of the scientists, said that various parameters are used to study cosmic objects. “Nearest branch of the astronomical messenger is gravitational waves. And LIGO was actually built to detect these waves. LIGO can detect when two gravitational waves merge,” said Bhattacharya.

LIGO-India to be effective by 2024

The planned LIGO-India detector will be funded by the Department of Atomic Energy (DAE) and the Department of Science and Technology (DST) and will increase the sensitivity of the international gravitational-wave network and produce many fold improvement to the localisation of the sources.

Tarun Souradeep, spokesperson for LIGO India, said, “It would be effective by 2024. We will be making a big difference.”

Astronomers will then be able to identify the exact location of the cosmic explosion a lot quicker and study right from the first moments in every frequency band of the electromagnetic spectrum. Scientist Sanjeev Dhurandhar said that gravitational ways may help discover a lot of things.
