Abstract
Dwarf Galaxies The Fornax Dwarf Spheroidal (dSph) is a satellite galaxy of the Milky Way. It contains unexpectedly numerous globular star clusters on wide orbits, which may indicate an unusual distribution of dark matter. Leung et al. constructed a semi-analytic model to explain the number and distribution of the globular clusters. They propose that the Fornax dSph is the result of a merger between two smaller dwarf galaxies about 10 billion years ago, which caused some globular clusters to be lifted to higher orbits and triggered the formation of others. The results are consistent with compositional data and constrain the Fornax dSph's dark matter profile. Mon. Not. R. Astron. Soc. 493 , 320 (2020).
