Context triple: [Edwin Hubble, knownFor, Hubble sequence of galaxy classification]
  • A. Zwicky catalog of galaxies
    The Zwicky catalog of galaxies is an influential astronomical catalog compiled by Swiss astronomer Fritz Zwicky that systematically lists and classifies thousands of galaxies and galaxy clusters.
  • B. Harvard spectral classification of stars
    The Harvard spectral classification of stars is an early 20th-century system that categorizes stars by their spectral characteristics and surface temperatures into types O, B, A, F, G, K, and M, forming the basis of modern stellar classification.
  • 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. Pillars of Creation
    Pillars of Creation is a famous Hubble Space Telescope image showing towering columns of interstellar gas and dust in the Eagle Nebula where new stars are being born.
  • E. Faber–Jackson relation paper
    The Faber–Jackson relation paper is a landmark astrophysics publication that established a correlation between the luminosity and stellar velocity dispersion of elliptical galaxies, providing key insights into their structure and evolution.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
