Context triple: [Jaan Einasto, notableConcept, Einasto density profile]
  • A. Milky Way stellar halo
    The Milky Way stellar halo is a vast, diffuse, roughly spherical population of old, metal-poor stars and dark matter that surrounds the Milky Way’s disk and bulge, extending far into its outer regions.
  • B. Galactic thin disk
    The Galactic thin disk is the relatively flat, rotating component of the Milky Way where most of its young to middle-aged stars, gas, and spiral arms are concentrated.
  • 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. Leo II Dwarf Galaxy
    Leo II Dwarf Galaxy is a faint, spheroidal dwarf galaxy and satellite of the Milky Way located in the constellation Leo and belonging to the Local Group of galaxies.
  • E. Leo I Dwarf Galaxy
    Leo I Dwarf Galaxy is a faint, spheroidal satellite galaxy of the Milky Way located in the constellation Leo and belonging to the Local Group of galaxies.
  • F. None of above. chosen
