COSMIC GEOMETRY. “It’s hard to measure the inner slope of the MW’s density profile, as baryons dominate at small radii. The large measured microlensing optical depth towards the Galactic centre implies large stellar densities in the inner MW, which appears to be in tension with the high DM densities at small radii of ‘cuspy’ density profiles.” (MW = Milky Way; DM = dark matter).
