Laser Interferometer Gravitational-Wave Observatory (LIGO)
Laser Interferometer Gravitational-Wave Observatory (LIGO), INDIA is a large-scale physics experiment aiming to detect gravitational waves directly. LIGO detector is 4-km arm-length Michelson Interferometer with Fabry-Perot enhanced cavities and aims to detect the space strain sensitivity better than 10–24 Hz–1/2.
LIGO-India is a collaborative project between LIGO USA and Department of Atomic Energy (DAE) (Govt. of India) for establishing an Advanced LIGO detector in India similar to that of LIGO-US (Hanford & Livingston observatories).
India’s major institutes (IPR-Gandhinagar, RRCAT-Indore, DCSEM and IUCAA-Pune) are participating in installation, commissioning and operation of the Gravitational Wave detector.
