  • A. TAMA 300 gravitational wave detector (historical)
    The TAMA 300 gravitational wave detector is a pioneering Japanese laser interferometer experiment that contributed to early gravitational wave research and technology development before the advent of larger observatories like LIGO and Virgo.
  • B. LIGO (Laser Interferometer Gravitational-Wave Observatory)
    LIGO (Laser Interferometer Gravitational-Wave Observatory) is a large-scale physics experiment and observatory designed to detect and study gravitational waves using highly sensitive laser interferometry.
  • C. IGO
    IGO is the ICAO airline designator for IndiGo, a major low-cost carrier based in India.
  • D. LIGO Scientific Collaboration
    The LIGO Scientific Collaboration is an international group of scientists and institutions that built and operate the LIGO detectors and made the first direct detection of gravitational waves, confirming a key prediction of Einstein’s general relativity.
