  • A. Gamma-Ray Burst Optical and Near-Infrared Detector
    The Gamma-Ray Burst Optical and Near-Infrared Detector (GROND) is a multi-channel astronomical instrument designed to simultaneously observe gamma-ray burst afterglows across optical and near-infrared wavelengths for rapid follow-up studies.
  • B. Gamma-ray Burst Monitor
    The Gamma-ray Burst Monitor is an instrument aboard NASA’s Fermi space telescope designed to detect and study gamma-ray bursts across a wide field of view.
  • C. X-ray polarimeter
    An X-ray polarimeter is a scientific instrument designed to measure the polarization properties of X-ray radiation, providing insights into the physical conditions and geometries of high-energy astrophysical sources.
  • D. Whipple 10-meter Gamma-Ray Telescope
    The Whipple 10-meter Gamma-Ray Telescope is a pioneering ground-based imaging atmospheric Cherenkov telescope used to detect very high-energy gamma rays from cosmic sources.
  • E. IXPE X-ray Polarimetry Explorer
    IXPE X-ray Polarimetry Explorer is a NASA space observatory designed to measure the polarization of cosmic X-rays to study extreme astrophysical environments such as black holes, neutron stars, and supernova remnants.
  • F. None of above. chosen
