The Laser Interferometer Gravitational-Wave Observatory (LIGO) - India is a planned advanced gravitational-wave observatory to be located in India as part of the worldwide network, whose concept proposal is now under active consideration in India and the USA. LIGO-India is envisaged as a collaborative project between a consortium of Indian research institutions and the LIGO Laboratory in USA, along with its international partners.
LIGO-India received the Indian Government's in-principle approval in February 2016. Since then the project reached several milestones towards selecting and acquiring a site and building the observatory.
A Gravitational Wave detector project on Indian soil
The LIGO-India project will be built by by the Department of Atomic Energy (DAE) and the Department of Science and Technology (DST), Government of India, with a Memorandum of Understanding (MoU) with the National Science Foundation (NSF), USA, along with several national and international research and academic institutions. The project is being led by four institutions:
How to get involved?
LIGO-India is intrinsically a multidisciplinary mega-science project that requires expertise from a variety of fields (e.g., laser, vacuum, optics, computer, etc., and of course Physics) and provides cutting edge research opportunities. There are multiple ways to get involved. Visit this page for more information.
