Phrase: Milky Way mass distribution | Statement: [Leo I Dwarf Galaxy, usedToStudy, Milky Way mass distribution]

Target entity: Milky Way mass distribution
Context triple: [Leo I Dwarf Galaxy, usedToStudy, Milky Way mass distribution]

• A. Milky Way dark matter halo chosen
  The Milky Way dark matter halo is the vast, roughly spherical, invisible mass of dark matter surrounding our galaxy that dominates its gravitational potential and governs the motions of its stars, gas, and satellite galaxies.
• B. 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.
• C. Milky Way globular cluster system
  The Milky Way globular cluster system is the population of ancient, densely packed star clusters that orbit the Milky Way’s halo and bulge, serving as key tracers of the galaxy’s formation and evolution.
• D. Schwarzschild method in galactic dynamics
  The Schwarzschild method in galactic dynamics is a numerical orbit-superposition technique used to construct self-consistent models of galaxies and infer their mass distributions, including dark matter and central black holes.
• E. Canis Major Overdensity
  The Canis Major Overdensity is a debated stellar overdensity near the plane of the Milky Way, often interpreted as either the remnant core of a disrupted dwarf galaxy or a warp/flare feature of the Galactic disk.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
