India and US are signing a memorandum of understanding (MoU) for building a state-of-the-art Ligo (Laser Interferometer Gravitational wave Observatory) project in the country, almost a month after the discovery of gravitational waves. The MoU will be signed between the National Science Foundation USA and India's Department of Atomic Energy and Department of Science and Technology.

The Ligo is a large-scale physics experiment and observatory to detect gravitational waves. Scientists involved in the project and the analysis of the data for gravitational-wave astronomy are organised by the LIGO Scientific Collaboration which includes more than 900 scientists worldwide, as well as 44,000 active Einstein@Home users.

LIGO is funded by the National Science Foundation (NSF), US, with important contributions from the UK Science and Technology Facilities Council, the Max Planck Society of Germany, and the Australian Research Council. Einstein@Home is a volunteer distributed computing project that searches through data from the LIGO detectors for evidence of continuous gravitational-wave sources.

The project was officially launched on 19 February 2005 as part of the American Physical Society's contribution to the World Year of Physics 2005 event. It uses the power ofvolunteer-driven distributed computing in solving the computationally intensive problem of analyzing a large volume of data.

The Indian government last month gave an "in-principle approval" for establishing the Ligo-India project which will establish a state-of-the-art gravitational wave observatory in India in collaboration with the Ligo Laboratory in the US, run by Caltech and MIT. The project will bring unprecedented opportunities for scientists and engineers to dig deeper into the realm of gravitational wave and take global leadership in this new astronomical frontier.

A meeting to decide the site for setting up the laboratory in India will be take place by April 10. Ligo-India will also bring considerable opportunities in cutting edge technology for the Indian industry which will be engaged in the construction of an 8 km-long beam tube at ultra-high vacuum on a levelled terrain.

The machines that gave scientists their first-ever glimpse at gravitational waves are the most advanced detectors ever built for sensing tiny vibrations in the universe. The two US-based underground detectors are known as the Laser Interferometer Gravitational-wave Observatory, or Ligo for short. One is located in Hanford, Washington and the other in Livingston, Louisiana.
