A Toy Model for the Dynamical Discrepancies on Galactic Scales
  In this study a simple toy model solution to the missing gravity problem on
galactic scales is reverse engineered from galactic data via imposing broad
assumptions. It is shown that the toy model solution can be written in terms of
baryonic quantities, is highly similar to pseudo-isothermal dark matter on
galactic scales and can accommodate the same observations. In this way, the toy
model solution is similar to MOND modified gravity in the Bekenstein-Milgrom
formulation. However, it differs in the similarity to pseudo-isothermal dark
matter and in the functional form. In loose terms, it is shown that
pseudo-isothermal dark matter can be written in terms of baryonic quantities.
The required form suggests that it may be worth looking into a mechanism that
can increase the magnitude of the post-Newtonian correction from general
relativity for low accelerations.
