Indian Initiative in Gravitational-wave Observations

IndIGO, the Indian Initiative in Gravitational-wave Observations, is an initiative to set up advanced experimental facilities, for a multi-institutional Indian national project in gravitational-wave astronomy.

  • The IndIGO Consortium includes Indian Institutes of Technology (IIT), Indian Institutes of Science Education and Research (IISER) and Delhi University, among others. Since 2009, the IndIGO Consortium has been involved in constructing the Indian road-map for Gravitational Wave Astronomy and a strategy towards Indian participation in realising the crucial gravitational-wave observatory in the Asia-Pacific region.
  • A new LIGO gravitational wave detector to be built in India by 2025
  • This will be the world’s third LIGO detector.
  • A new gravitational wave detector to measure ripples in the fabric of space and time is set to be built in India by 2025, in collaboration with universities from across the globe.

The new Laser Interferometer

  • Gravitational-Wave Observatory (LIGO) detector will add to the two already operational in the US. The LIGO detectors discovered the first gravitational waves produced by two giant merging blackholes last year. The research won a Nobel Prize in Physics this year.
  • The LIGO India partnership is funded by the Science and Technology Facilities Council (STFC) through its Newton-Bhabha project on LIGO.
  • The Raja Ramanna Centre for Advanced Technology in Indore and Institute for Plasma Research in Ahmedabad are in charge of building various parts of the system, said Raychaudhury. The mirrors and detectors required to build the system will be sent from the LIGO collaborators in the US.
  • LIGO-India is a planned advanced gravitational-wave detector to be located in India, to be built and operated in collaboration with the LIGO USA and its international partners Australia, Germany and the UK.
  • India’s first LIGO (Laser Interferometer Gravitational-Wave Observatory) laboratory will be set up in Aundh in Hingoli district of Maharashtra
