Density profiles (blue, left horizontal axis) and enclosed masses (orange, right horizontal axis) for the Plummer (solid) and cusp (dashed) profiles (Eq. (10)). The profiles have a scale parameter r₀ given by Eq. (14) and density parameters ρ₀ given by Eq. (15). The cusp exponent γ is given by Eq. (11). r_p and r_a denote the pericentre and apocentre distance of S2, respectively. The profiles are chosen such that 0.1% of the galactic centre MBH mass reside within r_a, i.e. they correspond to the current upper bound of GRAVITY Collaboration (2020).
