A gravity model for scientific mobility. a. By dividing the projected space into a grid, we can calculate aggregated densities and study their effect on flow patterns between grid elements. The resolution of the grid is fixed by the number of cells along any dimension \(N_{g}\). b. Fitted exponents from Eq. (1) for different grid resolution levels \(N_{g} = 10\), 25, 50, 75, 100. c. Comparison between predicted and observed mobility flows at a grid size resolution \(N_{g}=10\)
