  • A. Dark Energy Survey
    The Dark Energy Survey is a large international astronomical project that uses a wide-field camera on a Chilean telescope to map hundreds of millions of galaxies and study the nature of dark energy and cosmic acceleration.
  • B. SN 1572
    SN 1572 is a historically significant supernova in the constellation Cassiopeia whose detailed observations by Tycho Brahe helped challenge the Aristotelian view of an unchanging heavens.
  • C. Tolman surface brightness test
    The Tolman surface brightness test is an observational cosmology method that checks whether the universe is expanding by examining how the surface brightness of distant galaxies diminishes with redshift.
  • D. Carnegie Observatories
    Carnegie Observatories is a major astronomical research institution known for operating world-class telescopes and conducting cutting-edge studies of the universe.
  • E. Dark Energy Camera
    The Dark Energy Camera is a powerful wide-field astronomical imaging instrument designed to study dark energy and map the large-scale structure of the universe.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
