THE historic detection of gravitational waves (GW) made by the advanced Laser Interferometer Gravitational-wave Observatory (LIGO) detectors located in USA has opened the possibility of observing our universe in gravitational waves. The discovery announced on 11 February 2016 by the international LIGO Science Collaboration (LSC) has launched India onto an exciting arena of frontier science. Not only did the discovery paper have 39 Indian coauthor scientists from nine Indian institutions, but an opportunity for taking leadership in this field has opened up with the LIGO-India mega-science project.
LIGO-India is an ambitious, large scale mega-science project that will establish a state-of-the-art advanced LIGO gravitational wave (GW) observatory on Indian soil in collaboration with the LIGO Laboratory in the USA. LIGO-India is expected to commence science operations in 2024 as a key element of a global array of gravitational wave observatories. Beyond the first direct detection of gravitational waves announced in February 2016 by LIGO Science Collaboration, LIGO-India brings forth a great opportunity for Indian scientists and technologists for leadership at the frontier, a new window of gravitational-wave astronomy to probe the universe.
