Top panel: total gravitational field acting on a matter particle as a function of the gravitational field created by matter alone. A Newtonian regime can be observed for the high field region of the figure, with a gradual transition from the Newtonian regime to a MOND-like regime at an acceleration of ≈1.0 × 10⁻⁹ m s⁻². Middle panel: total gravitational field acting on a matter particle as a function of the gravitational field created by antimatter alone. The antimatter field is rather peaked, with an average value of ≈2 × 10⁻¹⁰ m s⁻². Bottom panel: ratio between the total gravitational field acting on a matter particle and the Newtonian field (created by matter only), as a function of the gravitational field created by matter only. Almost exactly unity in the Newtonian regime (at high values of the field), this ratio gradually increases and reaches a factor of ≈2 at the end of the depletion zone. The MOND interpolating function used in Lelli et al. (2019) for a value of the a₀ parameter 1.85 × 10⁻¹⁰ m s⁻² has been superimposed on the simulation data, while the two adjacent curves represent the 1-σ error of 0.11 dex found by these authors.
