Target entity: Supernova Cosmology Project
Context triple: [Alexei Filippenko, memberOf, Supernova Cosmology Project]
  • A. Carnegie Supernova Project
    The Carnegie Supernova Project is an astronomical research initiative focused on observing and characterizing supernovae to improve measurements of cosmic distances and the expansion of the universe.
  • B. The Large-Scale Structure of the Universe
    The Large-Scale Structure of the Universe is a foundational cosmology book by James Peebles that systematically develops the theory and observations of how matter is distributed on the largest cosmic scales.
  • C. 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.
  • D. 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.
  • E. Carnegie Irvine Galaxy Survey
    The Carnegie Irvine Galaxy Survey is an astronomical project that provides detailed optical imaging and analysis of nearby galaxies to study their structure, formation, and evolution.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
