Target entity: International Pulsar Timing Array
Context triple: [Max Planck Institute for Radio Astronomy, participatesIn, International Pulsar Timing Array]
  • A. International VLBI Service for Geodesy and Astrometry
    The International VLBI Service for Geodesy and Astrometry is an international organization that coordinates Very Long Baseline Interferometry observations to provide precise measurements of Earth’s rotation, reference frames, and celestial positions.
  • B. Very Long Baseline Interferometry
    Very Long Baseline Interferometry is a radio astronomy technique that combines signals from widely separated antennas to achieve extremely high angular resolution and precisely measure geodetic and astronomical parameters.
  • C. first binary pulsar PSR B1913+16
    PSR B1913+16 is a landmark binary pulsar system whose precisely measured orbital decay provided the first strong indirect evidence for the existence of gravitational waves, leading to a Nobel Prize in Physics.
  • 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.
  • E. Gravity Probe B experiment
    Gravity Probe B experiment was a NASA-led satellite mission designed to precisely measure how Earth's gravity warps space and time, providing a high-accuracy test of key predictions of Einstein's general relativity.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
